                          Vehicle Noise and Vibration - An Overview
                              Hua He, Jian Pang and Gang Sheng
                                  General Motors Corporation

Noise and vibration performance of a vehicle is increasingly linked to customer's perception of
vehicle quality and vehicle appeal. Sizable resources are spent in the industry, from OEMs to
suppliers, to achieve good N&V performance of vehicles. This presentation provides a
systematic overview of N&V in vehicles, the approaches adopted to improve N&V in vehicle
design and development. The presentation also discusses the challenges and opportunities of
N&V as more light-weight parts, hybrid systems and controls are used in vehicles.

                            Consumer Driven 6-Sigma: An Overview
                                         Larry Lloyd
                                      Generalety, LLC

What is Consumer Driven 6-Sigma and why are so many Fortune 500 companies using it as an
effective method to significantly improve quality and reduce cost? Quite simply, 6-Sigma is a
tool that improves customer satisfaction and shareholder value by reducing variability in every
aspect of a company’s business. It builds on existing processes, provides additional statistical and
analytical tools and offers a disciplined approach that focuses on meeting customer expectations.
6-Sigma allows a company to determine where the variability is in a process and then provides
the tools to reduce variability and improve the process. It’s important to realize that 6-Sigma
ultimately improves the things most companies do anyway and therefore rapidly becomes part of
the company’s “DNA”. It’s not something else they do . . . it is what they do!

Successful 6-Sigma companies find that the methodology improves productivity and shareholder
value by reducing the variability that leads to rework within processes. The improved processes
result in improved customer satisfaction, which increases the likelihood of customers returning to

buy another of the company’s products. The improved processes also reduce “hidden costs”
(inspections, reworks, recalls). Higher customer loyalty and reduced costs result in increased
shareholder value.

This presentation will provide insights into the following:
. Why it’s important to operate at a 6-Sigma level of quality
. Who uses 6-Sigma and how it’s use has escalated since Motorola’s initial efforts in 1982
. Organizational/philosophical changes that an organization must undergo to successfully
  implement and realize the benefits of 6-Sigma
. Some success stories

Larry Lloyd graduated from General Motors Institute (now Kettering University) with a degree
in Mechanical Engineering in 1970. In 1974, he added an MBA from Wayne State University.

Following his graduation from GMI, Mr. Lloyd spent two years working in the Fisher Body
R&D Department at the GM Tech Center. In 1972, he joined Ford Motor Company as a Product
Design Engineer and in 1977 became a Supervisor in the Light Truck Vehicle Programs
Department. From 1972 to 1990, Mr. Lloyd worked in various Light Truck Engineering
departments, including Durability, Cooling and Exhaust Design/Development, and Aerostar
Body Structure Design. In 1988, he was apppointed Program Supervisor for the all-new 1990 1/2
Explorer, which involved design and development coordination and leadership of the vehicle
launch at Louisville, Kentucky.

In 1990, Mr. Lloyd was promoted to 1992 Ranger Program Manager. The program involved
major freshening and FMVSS 208/219 compliance. His next assignment (1992) was Compact
Truck Powertrain Programs Manager in which he coordinated design and development of
Explorer/Ranger/Aerostar 4.0L SOHC engine and A5LDE transmission programs in Germany,
England and France. These new powertrains were successfully launched at Job #1, 1995.

In October, 1994, Mr. Lloyd was transferred from Light Truck Engineering to Car Engineering
and became Vehicle Engineering Manager for the all-new 1994 1/2 Windstar minivan. In this
position, he was responsible for durability, NVH, dynamics, crash testing and packaging and was
the Launch Manager at the Oakville, Ontario Assembly Plant. Mr. Lloyd continued as Windstar
Vehicle Engineering Manager from 1995 through 1999 model years, with 1999 being a major
upgrade/freshening program.

In January, 2000, Mr. Lloyd was appointed North American Car 6-Sigma Deployment Director.
In this capacity, he was responsible for 6-Sigma strategy, deployment and implementation plans
for Mustang, Windstar, Villager, Focus, Taurus and Sable at seven (7) assembly plants and for
1700 Dearborn-based Product Development personnel. North American Car’s first year results
were approximately $88 mil in cost savings and several percentage points improvement in
customer satisfaction for Mustang, Focus and Windstar.

After 30 years with Ford, Mr. Lloyd retired in 2002. Since that time, he has worked as a
financial and legal planning seminar speaker and, most recently, joined Generalety, LLC, as
Chief Program Engineer.

                     Superplasticity: From Aerospace to Automotive
                                          Xin Wu

Superplasticity is a phenomenon that at certain temperature and strain rate some materials can be
plastically stretched to hundreds, even thousands of percents of their original lengths without
fracture, at a stress significantly lower than that at room temperature. Scientists were curious
what made these materials so special, and would it be possible we shape engineering materials
this way so complex parts might be made cheap. This scientific curiosity eventually leads to
Superplastic Forming (SPF), a new and very important manufacturing technology. In the past
twenty-five ears there has been a remarkable evolution of SPF in aerospace industry for making
small volume components with very complex geometry and large deformation that otherwise
very difficult to made or require much higher manufacturing cost. The limitation of SPF is it’s
very slow forming speed, making it difficult for large volume production, required for
automotive industry.

Within the last ten years significant progress has been made in high strain rate superplasticity,
and in the development of superplastic materials. It is now clear that the mechanism of
superplasticity is related to grain boundary sliding, which can occur for wide-range materials
with fine-grained and stable microstructures. In order to speed up the forming process without
losing superplasticity or acceptable formability for automotive applications significant efforts
have been made in the areas of material development, tooling, and process/product design. Very
recently GM has disclosed their Quick Plastic Forming process, which allows aluminum
components to be formed with large deformation at a competitive speed and cost to conventional
sheet metal stamping process. In addition, US government has supported an automotive oriented
metal forming technology development, called Hot Metal Gas Forming, with the research base at
Wayne State University. Both forming processes can be considered as the extension of SPF.

Recently it has been found that when materials are refined to a nanometer scale they exhibit
many extraordinary behavior, which are superior than any previously existing materials, for
example, steels with that scale of grain size can be plastically deformed to 0ver 1000%
elongation at high temperature, and after forming and cool to room temperature the strength can
be over 1 GPa. Some new materials such as carbon nanotube is found to have a strength 100
times of steels. The new discovery of the nano-materials provides great opportunity for
superplastic forming at much reduced manufacturing cost and with much improved post-forming
In this presentation the historical review of the superplasticity, current state-of-the-art, some
personal research results future perspectives will be provided.

                                United States Steel Corporation

Everyone has been well aware of the China’s exceptional economic development since the
1980’s. What no one anticipated, however, was the phenomenal growth of the Chinese auto and
steel industry over the last few years.

In 2003, China has become number three in the world in vehicle production and every major
auto company has entered China market. The questions are: Is it sustainable? Is it accidental?
What will auto industry look like in five year? Who will be the major players?

Like the auto industry, the suddenly increased steel demands in China have resulted in
worldwide raw material shortages and have caused “red hot” steel markets worldwide, including
North America. One presentation from last October’s International Iron & Steel Institute
conference entitled “Vacuum Cleaning the World: China & Steelmaking Raw Materials”. This
title pretty much tells the story of China’s current impact on world steel industry.

This presentation will give an overview on China’s auto and steel industry and some forecasts on
future development.

Dr. Ming F. Shi is currently the technical manager of advanced applications technology within
automotive product technology group at the Automotive Center of United States Steel
Corporation. The group consists of leading experts in the industry within the areas of
forming/stamping, computer simulations, structural performance and analysis, welding and
joining as well as materials, structural and mechanical test laboratories.

Ming joined United Steel Corporation in 1997. Prior to that, he worked at Product Applications
Center of National Steel Corporation for 7 ½ years as a leading forming engineer. He has
authored/co-authored more than 40 technical papers in the areas of sheet metal forming, dent
resistance, tailored welded blanks applications, material constitutive modeling and computer

simulations. He served as an executive board member of North America Deep Draw Research
Group and session organizer and chairman for the body manufacturing and assembly track of
International Body Engineering Conference (IBEC).

Ming received the B.S. in engineering mechanics from Hohai University in Nanjing, China and
the M.S. and Ph.D. in mechanical engineering and engineering mechanics from Michigan
Technological University, Houghton, Michigan.
