Theory of Energy Absorption Enidine Incorporated
Overview

Theory of Energy Absorption

As companies strive to increase productivity by operating machinery at higher speeds, often the results are increased noise, damage to machinery/products, and excessive vibration. At the same time, safety and machine reliability are decreased. A variety of products are commonly used to solve these problems. However, they vary greatly in effectiveness and operation. Typical products used include rubber bumpers, springs, cylinder cushions and shock absorbers. The following illustrations compare how the most common products perform:

The advantages of using shock absorbers include: 1. Longer Machine Life – The use of shock absorbers significantly reduces shock and vibration to machinery. This eliminates machinery damage, reduces downtime and maintenance costs, while increasing machine life. 2. Higher Operating Speeds – Machines can be operated at higher speeds because shock absorbers control or gently stop moving objects. Therefore, production rates can be increased. 3. Improved Production Quality – Harmful side effects of motion, such as noise, vibration and damaging impacts, are moderated or eliminated so the quality of production is improved. Therefore, tolerances and fits are easier to maintain. 4. Safer Machinery Operation – Shock absorbers protect machinery and equipment operators by offering predictable, reliable and controlled deceleration. They can also be designed to meet specified safety standards, when required. 5. Competitive Advantage – Machines become more valuable because of increased productivity, longer life, lower maintenance costs and safer operation.

Automotive vs. Industrial Shock Absorbers
It is important to understand the differences that exist between the standard automotive-style shock absorber and the industrial shock absorber. The automotive style employs the deflective beam and washer method of orificing. Industrial shock absorbers utilize single orifice, multi-orifice and metering pin configurations. The automotive type maintains a damping force which varies in direct proportion to the velocity of the piston, while the damping force in the industrial type varies in proportion to the square of the piston velocity. In addition, the damping force of the automotive type is independent of the stroke position while the damping force associated with the industrial type can be designed either dependent or independent of stroke position.

All moving objects possess kinetic energy. The amount of energy is dependent upon weight and velocity. A mechanical device that produces forces diametrically opposed to the direction of motion must be used to bring a moving object to rest. Rubber bumpers and springs, although very inexpensive, have an undesirable recoil effect. Most of the energy absorbed by these at impact is actually stored. This stored energy is returned to the load, producing rebound and the potential for damage to the load or machinery. Rubber bumpers and springs initially provide low resisting force which increases with the stroke. Cylinder cushions are limited in their range of operation. Most often they are not capable of absorbing energy generated by the system. by design, cushions have a relatively short stroke and operate at low pressures resulting in very low energy absorption. The remaining energy is transferred to the system, causing shock loading and vibration. Shock absorbers provide controlled, predictable deceleration. These products work by converting kinetic energy to thermal energy. More specifically, motion applied to the piston of a hydraulic shock absorber pressurizes the fluid and forces it to flow through restricting orifices, causing the fluid to heat rapidly. The thermal energy is then transferred to the cylinder body and harmlessly dissipated to the atmosphere.

Theory of Energy Absorption Enidine Incorporated
Overview
Equally as important, automotive-style shock absorbers are designed to absorb only a specific amount of input energy. This means that, for any given geometric size of automotive shock absorber, it will have a limited amount of absorption capability compared to the industrial type. This is explained by observing the structural design of the automotive type and the lower strength of materials commonly used. These materials can withstand the lower pressures commonly found in this type. The industrial shock absorber uses higher strength materials, enabling it to function at higher damping forces.

Shock Absorber Performance When Weight or Impact Velocity Vary
When conditions change from the original calculated data or actual input, a shock absorber’s performance can be greatly affected, causing failure or degradation of performance. Variations in input conditions after a shock absorber has been installed can cause internal damage, or at the very least, can result in unwanted damping performance. Variations in weight or impact velocity can be seen by examining the following energy curves: Varying Impact Weight: Increasing the impact weight (impact velocity remains unchanged), without reorificing or readjustment will result in increased damping force at the end of the stroke. Figure 1 depicts this undesirable bottoming peak force. This force is then transferred to the mounting structure and impacting load.

Theory of Energy Absorption

Adjustment Techniques
A properly adjusted shock absorber safely dissipates energy, reducing damaging shock loads and noise levels. For optimum adjustment setting see useable adjustment setting graphs. Watching and “listening” to a shock absorber as it functions aids in proper adjustment.

Damping Force Min. Max.

To correctly adjust a shock absorber, set the adjustment knob at zero (0) prior to system engagement. Cycle the mechanism and observe deceleration of the system. If damping appears too soft (unit strokes with no visual deceleration and bangs at end of stroke), move indicator to next largest number. Adjustments must be made in gradual increments to avoid internal damage to the unit (e.g., adjust from 0 to 1, not 0 to 4). Increase adjustment setting until smooth deceleration or control is achieved and negligible noise is heard when the system starts either to decelerate or comes to rest. When abrupt deceleration occurs at the beginning of the stroke (banging at impact), the adjustment setting must be moved to a lower number to allow smooth deceleration. If the shock absorber adjustment knob is set at the high end of the adjustment scale and abrupt deceleration occurs at the end of the stroke, a larger unit may be required. Figure 1 Varying Impact Velocity: Increasing impact velocity (weight remains the same) results in a radical change in the resultant shock force. Shock absorbers are velocity conscious products; therefore, the critical relationship to impact velocity must be carefully monitored. Figure 2 depicts the substantial change in shock force that occurs when the velocity is increased. Variations from original design data or errors in original data may cause damage to mounting structures and systems, or result in shock absorber failure if the shock force limits are exceeded.

Overview
SHOCK ABSORBER SIZING
Follow the next six steps to manually size Enidine shock absorbers: STEP 1: Identify the following parameters. These must be known for all energy absorption calculations. Variations or additional information may be required in some cases. A. Weight of the load to be stopped (Kg). B. Velocity of the load upon impact with the shock absorber (m/s). C. External (propelling) forces acting on the load (N), if any. D. Cyclic frequency at which the shock absorber will operate. E. Orientation of the application’s motion (i.e. horizontal, vertical up, vertical down, inclined, rotary horizontal, rotary vertical up, rotary vertical down). NOTE: For rotary applications, it is necessary to determine both the radius of gyration (K) and the mass moment of inertia (I). both of these terms locate the mass of a rotating object with respect to the pivot point. It is also necessary to determine the angular velocity (ω) and the torque (T). STEP 2: Calculate the kinetic energy of the moving object. EK = I ω2 (rotary) or EK = 1 MV2 (linear) 2 2 Utilizing the Product Locators for Shock Absorbers located at the beginning of each product family section, select a model, either adjustable or non-adjustable, with a greater energy per cycle capacity than the value just calculated. STEP 3: Calculate the work energy input from any external (propelling) forces acting on the load, using the stroke of the model selected in Step 2. T EW = FD x S (linear) or EW = R x S (rotary) S Caution: The propelling force must not exceed the maximum propelling force listed for the model chosen. If the propelling force is too high, select a larger model and recalculate the work energy. STEP 4: Calculate the total energy per cycle E T = E K + E W The model selected must have at least this much energy capacity. If not, select a model with greater energy capacity and return to Step 3. STEP 5: Calculate the energy that must be absorbed per hour. Even though the shock absorber can absorb the energy in a single impact, it may not be able to dissipate the heat generated if the cycle rate is too high. E TC = E T x C The model selected must have an energy per hour capacity greater than this calculated figure. If it is not greater, there are two options: 1. Choose another model that has more energy per hour capacity (because of larger diameter or stroke). Keep in mind that if the stroke changes, you must return to Step 3. 2. Use an Air/Oil Tank. The increased surface area of the tank and piping will increase the energy per hour capacity by 20 percent. STEP 6: If you have selected an HP, PM, SPM, TK, or PRO Series model, refer to the sizing graph(s) in the appropriate series section to determine the required damping constant. If the point cannot be found in the sizing graph, you must select a larger model or choose a different series. Note that if the stroke changes, you must return to Step 3. If you have selected an adjustable model (OEM, HP or HDA series), refer to the Useable Adjustment Setting Range graph for the chosen model. The impact velocity must fall within the limits shown on the graph.

RATE CONTROL SIZING

Follow the next five steps to manually size Enidine rate controls: STEP 1: Identify the following parameters. These must be known for all rate control calculations. Variations or additional information may be required in some cases. A. Weight of the load to be controlled Kg B. Desired velocity of the load m/s C. External (propelling) force acting on the load N, if any. D. Cyclic frequency at which the rate control will operate. E. Orientation of the application’s motion (i.e. horizontal, vertical up, vertical down, inclined, rotary horizontal, rotary vertical up, rotary vertical down.) F. Damping direction (i.e., tension [T], compression [C] or both [T and C]. G. Required stroke mm NOTE: For rotary applications, please submit the application worksheet on page 108 to Enidine for sizing. STEP 2: Calculate the propelling force at the rate control in each direction damping is required. (See sizing examples on page 6-12). CAUTION: The propelling force in each direction must not exceed the maximum propelling force listed for the chosen model. If the propelling force is too high, select a larger model. STEP 3: Calculate the total energy per cycle ET = EW (tension) + EW (compression) EW = FD x S STEP 4: Calculate the total energy per hour E TC = E T x C The model selected must have an energy per hour capacity greater than this calculated figure. If not, choose a model with a higher energy per hour capacity. Compare the damping direction, stroke, propelling force, and total energy per hour to the values listed in the Rate Controls Engineering Data Charts (pages 109-114). STEP 5: If you have selected a rate control, refer to the sizing graphs in the Rate Controls section to determine the required damping constant. If you have selected an adjustable model (ADA), refer to the Useable Adjustment Setting Range graph for the chosen model. The desired velocity must fall within the limits shown on the graph.

Overview

Adjustable Series

OEM Large Series OEM Xtreme Mid-Bore Series

OEM Small Bore Platinum Series

Enidine Adjustable Hydraulic Series shock absorbers offer the most flexible solutions to energy absorption application requirements when input parameters vary or are not clearly defined. By simply turning an adjustment knob, the damping force can be changed to accommodate a wide range of conditions. Enidine offers the broadest range of adjustable shock absorbers and mounting accessories in the marketplace today. The Enidine OEMXT Series provides a low profile adjustment knob offered in metric or imperial thread configurations with stroke lengths of 25 to 150 mm for drop-in competitive interchange. Low Range (LROEMXT) Series products are also available to control velocities as low as 0,08 m/s and propelling forces as high as 17 790 N. OEMXT and OEM Large Series shock absorbers are fully field repairable.

Features and Benefits
• Adjustable design lets you “fine-tune” your desired damping and lock the numbered adjustment setting. • Internal orifice design provides deceleration with the most efficient damping characteristics, resulting in the lowest reaction forces in the industry. • Threaded cylinders provide mounting flexibility and increased surface area for improved heat dissipation. • Incorporated optional fluids and seal packages can expand the standard operating temperature range from (-10°C to 80°C) to (–30°C to 100°C) • ISO quality standards result in reliable, long-life operation. • Operational parameters can be expanded through the use of Enidine’s Low Range and High Performance products. • Fully field repairable units are available in mid-bore and larger bore product ranges. • Custom orificed non-adjustable units (CBOEM) can be engineered to meet specific application requirements. • A select variety of surface finishes maintains original quality appearance and provides the longest corrosion resistance protection.

Adjustable Series Hydraulic Shock Absorbers OEM Series
Overview
Enidine Adjustable Single Orifice Shock Absorbers
Piston Rod

OEM XT

Adjustable Series

Foam Accumulator Check Ring Bearing Coil Spring Piston Head

Conventional damping allows linear deceleration by providing a constant shock force over the entire stroke. This standard design is the most efficient, meaning it allows the most energy to be absorbed in a given stroke, while providing the lowest shock force. This type of damping is also available in adjustable shock absorbers.

Adjustment Knob Cylinder Oil Shock Tube Orifice

The damping force of an Enidine single orifice shock absorber can be changed by turning the adjustment knob. Maximum damping force is achieved by turning the adjustment knob to eight (8), while minimum damping force is achieved by turning the adjustment knob to zero (0). Turning the adjustment knob causes the adjustment ball to increase or decrease the clearance (orifice area) between the ball and its seat, depending on rotation direction. The internal structure of an adjustable single orifice shock absorber is shown above. When force is applied to the piston rod, the check ball is seated and the valve remains closed. Enidine Adjustable Multiple Orifice Shock Absorbers

Oil is forced out of the high pressure shock tube chamber through the orifice, creating internal pressure allowing smooth, controlled deceleration of the moving load. When the load is removed, the compressed coil spring moves to reposition the piston head, the check ball unseats, opening the valve that permits rapid piston rod return to the original extended position. The closed cellular foam accumulator compensates for fluid displaced by the piston rod during compression and extension. Without the fluid displacement volume provided by the foam accumulator, the closed system would be hydraulically locked. This type of orifice design results in.

Coil Spring Check Ring Adjustment Cam Piston Rod Adjustment Knob Orifice Holes Bearing Adjustment Pin Cylinder Shock Tube

Constant orifice area damping (dashpot) provides the largest shock force at the beginning of the stroke when impact velocity is highest. These shock absorbers provide high-energy absorption in a small, economical design. This type of damping is also available in adjustable shock absorbers.

Piston Head Foam Accumulator Oil

The adjustable multiple orifice shock absorber is similar to the principles described earlier. The check ring replaces the check ball and the adjustment feature uses an adjustment pin instead of an adjustment ball. The damping force of the shock absorber can be changed by turning the adjustment knob. Maximum damping force is achieved by turning the adjustment knob to eight (8), while minimum damping force is achieved by turning the adjustment knob to zero (0).

Turning the adjustment knob rotates the adjustment cam within the shock absorber. The cam, in turn, moves the adjustment pin in the shock tube, closing or opening the orifice holes. by closing the orifice holes, the total orifice area of the shock absorber is reduced, thus increasing the damping force of the shock absorber. The adjustable shock absorber enables the user to change the damping force of the unit, should input conditions change, while still maintaining a conventional-type damping curve. Low velocity range (LR) series configurations are available for controlling velocities that fall below the standard adjustable range.

Adjustment Techniques
After properly sizing the shock absorber, the useable range of adjustment settings for the application can be determined: Example: OEM 1.25M x 1 1. Impact Velocity: 2. Intersection Point: 3. Useable Adjustment: 1. Impact Velocity: 2. Intersection Point: 3. Useable Adjustment: 1,0 m/s Adjustment Setting 5 Setting Range 0 to 5 .5 m/s Adjustment Setting 3 Setting Range 0 to 3

Adjustable Series

1. Locate the intersection point of the application’s impact velocity and the selected model graph line. 2. The intersection is the maximum adjustment setting to be used. Adjustments exceeding this maximum suggested setting could overload the shock absorber. 3. The useable adjustment setting range is from the 0 setting to the maximum adjustment setting as determined in step 2.

Example: (LR)OEMXT 2.0M x 2

Useable Adjustment Setting Range
5,0 4,5

Position 0 provides minimum damping force. Position 8 provides maximum damping force.

Cylinder Piston Rod

Check Ball Piston Head Bearing

Foam Accumulator Orifice Coil Spring Piston Stop Plug

Constant orifice area damping (dashpot) provides the largest shock force at the beginning of the stroke when impact velocity is highest. These shock absorbers provide high-energy absorption in a small, economical design. The internal structure of a single orifice shock absorber is shown above. When a force is applied to the piston rod, the check ball is seated and the valve remains closed. Oil is forced through the orifice, creating internal pressure allowing smooth, controlled deceleration of the moving load. When the load is removed, the compressed coil spring moves to reposition the piston head, the check ball unseats, opening the valve that permits rapid return of the piston head rod to the original extended position. The closed cellular foam accumulator is compressed by the oil during the stroke, compensating for fluid displaced by the piston rod during compression. Without the fluid displacement volume provided by the foam accumulator, the closed system would be hydraulically locked. Single-orifice shock absorbers provide constant orifice area (dashpot) damping.

PM 15/100 Small-Bore Series

Enidine non-adjustable hydraulic shock absorbers can accommodate varying energy conditions. This family of tamperproof shock absorbers provides consistent performance, cycle after cycle. Non-adjustable models are designed to absorb maximum energy within a compact envelope size. The PM Series uses a self-compensating design to provide energy absorption in low velocity and high drive force applications. The Platinum PM Series also includes the added benefit of corrosion-resistant, nickel-plated components and positive stop capabilities. Models can accommodate a wide range of operating conditions with varying masses or propelling forces. The Platinum PRO Series has unique progressive damping and a multi-orifice design that provides softer stops for medium-to-high impact velocities and fragile loads. The Platinum PRO Series also includes the added benefit of corrosion-resistant, nickel-plated components and positive stop capabilities. Models can accommodate a wide range of operating conditions.

Features and Benefits
• Extensive non-adjustable product line offers flexibility in both size and energy absorption capacity to fulfill a wide range of application requirements. • Tamperproof design ensures repeatable performance. • Special materials and finishes can be designed to meet specific customer requirements. • Incorporating optional fluids and seal packages can expand the standard operating temperature range from (-10°C to 80°C) to (–30°C to 100°C). • Threaded cylinders provide mounting flexibility and increase surface area for improved heat dissipation. • A select variety of surface finishes maintains original quality appearance and provides the longest corrosion resistance protection. • ISO quality standards result in reliable, long-life operation.

PM Overview

Check Ring Piston Head Bearing Orifice Hole Location

Foam Accumulator Oil Coil Spring

Shock Tube

Progressive damping provides deceleration with a gradually increasing shock force. The initial minimal resistance at impact protects delicate loads and machinery from damage. Progressive damping shock absorbers also have built-in self-compensation, so they can operate over a wide range of weights and velocities. This type of damping provides smooth deceleration in applications where energy conditions may change.

Self-compensating damping maintains acceptable deceleration with conventional type damping characteristics. Self-compensating shock absorbers operate over a wide range of weights and velocities. These shock absorbers are well suited for high drive force, low velocity applications, and where energy conditions may change. Curve A shows the shock force vs. stroke curve of a self-compensating shock absorber impacted with a low velocity and high drive force. Curve B shows the shock force vs. stroke curve of a self-compensating shock absorber impacted with a high velocity and low drive force.

The design of a multi-orifice shock absorber features a double cylinder arrangement with space between the concentric shock tube and cylinder, and a series of orifice holes drilled down the length of the shock tube wall. During piston movement, the check ring is seated and oil is forced through the orifices in the shock tube wall, into the closed cellular foam accumulator and behind the piston head.

As the piston head moves it closes off orifice holes, thus reducing the available orifice area in proportion to the velocity. After the load is removed the coil spring pushes the piston rod outward. This unseats the check ring and permits the oil to flow from the accumulator and across the piston head, back into the shock tube. This allows quick repositioning for the next impact. Low Pressure multiple orifice shock absorbers can provide progressive or self-compensating damping, depending on the impact conditions.

ADA DA

Rate Controls ADA/DA Series
Overview

Rate Controls

ADA Series

Tow Bar Snubbers

DA Series

Enidine Rate Controls are designed to regulate the speed and time required for a mechanism to move from one position to another. Adjustable and non-adjustable models are available to accommodate a wide variety of motion control applications. both single and double acting hydraulic damper designs allow smooth, controllable machine operation by providing rate control for both linear and rotational (hinged) loads. Each product family offers a variety of stroke lengths from which to choose. Adjustable, Double Acting (ADA 500M and ADA 700M Series) rate controls regulate speed in both tension and/or compression modes independently. ADA products let the user adjust the rate to suit specific application requirements. Fixed orifice interchangeable cartridges are available for the ADA 500M Series, which provide tamperproof operation once the desired rate has been determined. An optional remote adjustment cable provides adjustment control in otherwise inaccessible locations for the ADA 500M Series. The DA Series are non-adjustable, custom-orificed at factory, double acting rate controls which provide smooth, reliable motion control for high load capacities.

Adjustable Double Acting (ADA) Series Rate Control

ADA DA Overview

Piston Head Piston Clevis Shock Tube Cylinder Bearing Piston Rod Oil Cylinder End Foam Accumulator Check Ball Orifice Compression Adjustment Cartridge Tension Adjustment Cartridge

Rate Controls

Enidine Double Acting Adjustable (ADA) rate controls control the velocity of both linear and rotational loads throughout their entire motion. Adjustment cartridges on the ADA 500M Series allow flexibility in controlling the speed for an applied force in both the tension and compression directions. Maximum damping is achieved by turning the adjustment knob to the number eight (8) setting, while turning the knob to the zero (0) setting provides minimal resistance. Interchangeable, threaded, fixed-orifice cartridges can provide consistent, tamper-resistant damping to meet particular application requirements. The ADA 500M Series utilizes two independent adjustment cartridges for motion control in each direction, housed in the cylinder end. The ADA 700M Series has independently controlled tension and compression capabilities located at each end of the unit.

Resistance is controlled by using a wrench key at either end of the rate control and adjusting the movement by following the stiffer (+) or softer (-) indications. When the rate control is compressed, the oil is orificed through the compression adjustment cartridge and flows freely through the tension adjustment cartridge. The tension cartridge check ball unseats and allows free flow of the oil to the rod end of the shock tube. A foam accumulator is utilized to accept the volume of oil displaced by the piston rod. When the rate control is extended, oil is moved through an internal flow path in the shock tube and is orificed through the tension adjustment cartridge. The compression cartridge check ball unseats and allows free flow of the oil into the blind end of the shock tube.

Extension Check Ball Orifice Hole(s) Cylinder Piston Clevis Piston Rod Bearing Foam Accumulator Piston Head Compression Check Ball Shock Tube Oil

DA Series rate controls are ideally suited for high-energy, heavy load applications requiring rate control in tension, compression or both directions. These non-adjustable, custom-orificed units are designed to specific input conditions, and allow for single and multiple orifice configurations. Upon compression of the rate control, the compression check ball seats. As the piston head moves, oil is forced through the orifice hole(s) located in the shock tube, producing the required damping force. After the oil has

passed through the orifice hole(s), a portion of the oil passes through the extension check valve and fills the rod end of the shock tube. The remainder of the oil volume displaced by the piston rod compresses the foam accumulator. Upon extension of the rate control, the extension check ball seats. As the piston head moves, oil is forced through the orifice hole(s) located in the shock tube producing the required damping force. The compression check ball is unseated by the flow of oil which fills the blind end of the shock tube.

Rate Controls ADA/DA Series
Overview
Enidine Rate Controls are used to regulate the speed or time required for a mechanism to move from one position to another. They use proven technology to enhance performance in a variety of product applications. Rate controls are typically used to control pneumatic cylinders, linear slides, lids, and other moving mechanisms. The advantages of using rate controls include: 1. Longer Machine Life – The use of rate controls significantly reduces shock and vibration to machinery caused by uncontrolled machine operation. This further reduces machinery damage, downtime and maintenance costs, while increasing machine life. 2. Improved Production Quality – Harmful effects of uncontrolled motion, such as noise, vibration and damaging impacts, are moderated or eliminated so that production quality is improved. 3. Safer Machinery Operation – Rate controls protect machinery and equipment operators by offering predictable, reliable and controlled machine operation. 4. Competitive Advantage – Machines and end products become more valuable because of increased productivity, longer life, lower maintenance and safer operation. Enidine offers a wide range of rate controls that provide motion control in tension, compression, or both directions. Adjustable and non-adjustable tamperproof models are available to fit your particular application requirements. The resisting force provided by Enidine rate controls is typically constant over the entire stroke when the piston rod is moved at a constant velocity, since the rate controls are single orifice products. DA Series models can be custom orificed to provide increasing resisting force over the stroke through the use of multiple orifices in the shock tube. This can be beneficial when controlling the velocity of a lid as it closes, since the torque from the weight of the lid changes as it closes.

Rate Control Adjustment Techniques
A properly adjusted rate control safely controls machinery operation, and reduces noise levels from uncontrolled motion. To correctly adjust the rate control after it has been properly sized for the application, set the adjustment knob (per the useable adjustment setting graphs for the applicable model. Cycle the mechanism and observe the motion of the system. If the motion of the mechanism is too fast, move the adjustment dial to the next largest number until the desired velocity is achieved. If the motion of the mechanism is too slow, move the adjustment dial to the next smallest number until the desired velocity is achieved.

Position 0 provides minimum damping force. Position 8 provides maximum damping force. 180° adjustment with setscrew locking.

1. Determine the damping direction (tension [T], compression [C] or both [T and C]), stroke (mm) required, propelling force (N), desired velocity (m/s) and cycles per hour. 2. Calculate total energy per hour (Nm/hr). 3. Compare the damping direction (T, C, or T and C), stroke (mm) required, propelling force (N) and total energy per hour (Nm/hr) to the values listed in the Rate Controls Engineering Data charts. NOTE: Propelling force and velocity should be measured at the location of the rate control. 4. Determine if adjustable or non-adjustable model is desired. 5. Select the appropriate rate control model. A. For adjustable rate control models, refer to the Useable Adjustment Settings section for the selected model to determine the proper adjustment setting. B. For non-adjustable rate control models, refer to the Damping Constant Selection Instructions for the selected model to determine the proper damping constant. Example: 1. Damping Direction (T, C or T and C): Stroke (S): Propelling Force (FD): Velocity (V): Cycles/Hour (C): T and C 102 mm 890 N (T and C) 0,2 m/s 20

After properly sizing the ADA, the adjustment setting can be determined.

1. To determine the approximate adjustment setting when the selected model, propelling force, and velocity are known: compare velocity to the propelling force in the compression and/or tension mode adjustment setting curves. The intersection point of the velocity and the propelling force is the approximate adjustment setting to be used. Adjustment higher or lower than this setting will result in slower or faster damper operation, respectively. 2. To determine the velocity when the selected model, adjustment setting, and propelling force are known: compare the propelling force to the adjustment setting in the compression and/or tension mode adjustment setting curves. The intersection point of the propelling force and the adjustment setting is the approximate velocity for the selected model. Higher velocities are obtained at lower adjustment settings and lower velocities are obtained at higher adjustment settings. EXAMPLE: Double Acting Application Stroke required: 51 mm Control direction: Tension and Compression Propelling force: 1 557 N (tension), 1 780 N (compression) Selection: ADA 505 1. Velocity: 0,28 m/s (tension), 0,15 m/s (compression) Intersection point: Adjustment setting 2 (tension), 4 (compression) 2. Adjustment setting: 2 (tension), 4 (compression) Velocity: 0,28 m/s (tension), 0,15 m/s (compression) NOTE: When a free flow plug is used, the intersection point of the propelling force and free flow plug curve determines the velocity. NOTE: Propelling force and velocity should be measured at the location of the rate control.

2. Total Energy/Hour: 1 808 Nm/hr compression 1 808 Nm/hr tension 3 616 Nm/hr Total 3. Compare damping direction (T and C), stroke, propelling force and total energy per hour, to the values listed in the rate controls engineering data charts. 4. An adjustable model is desired. 5. Selection: ADA 510M (T and C), The proper adjustment is two (2) in tension and compression per the ADA 500M Series Useable Adjustment Setting Range Curves.

Notes: 1. DA Models will function at 10% of their maximum rated energy per cycle. If less than 10%, a smaller model should be specified. 2. Provide a positive stop 3 mm before end of stroke in tension and compression to prevent internal bottoming. 3. For optimal performance in vertical applications using compression, mount the rate control with the piston rod down.

Notes: 1. DA Models will function at 10% of their maximum rated energy per cycle. If less than 10%, a smaller model should be specified. 2. Provide a positive stop 3 mm before end of stroke in tension and compression to prevent internal bottoming. 3. For optimal performance in vertical applications using compression, mount the rate control with the piston rod down. 4. * ØS indicates outside diameter of optional protective sleeve for TB 100M x 100 models. 5. ** Dimension L is controlled by a 50 mm stroke limiter.
