Automotive Chassis Design & NVH Performance
A chassis is the supporting frame of a car. It gives the car strength and rigidity, and helps increase the car's crash-resistance through energy absorption. If a car were a human body, the chassis would be the skeleton. During a fall, a person with strong bones is likely to be hurt less than someone with weak bones. The same goes for a car in an accident. The chassis helps keep a vehicle rigid. A strong chassis will keep the back end of a car from falling out of alignment with the front end, while remaining as stiff and unbending as possible.
The chassis is especially
important in ensuring low levels of noise, vibration and harshness (NVH)
throughout the vehicle. Not only does a reduction in NVH allow for a more
pleasant driving experience, but by putting less stress on connecting
components it can help increase the life span of these components. The key
determinant permitting reduced levels of NVH is energy absorption. By having a
high level of energy absorption, NVH levels are lowered, but more importantly,
passenger protection can be enhanced in the event of a collision.

Ford background
Ford Motor Company, American automotive corporation founded
in 1903 by Henry Ford and 11 associate investors. In 1919 the company was
reincorporated, with Ford, his wife, Clara, and his son, Edsel, acquiring full ownership; they, their heirs,
and the Ford
Foundation (formed 1936) were sole stockholders
until January 1956, when public sale of the common stock was first offered. The
company manufactures passenger cars, trucks, and tractors as well as automotive parts and
accessories. Headquarters are in Dearborn, Michigan.
U.S. automotive corporation. Founded in Detroit,
Mich., in 1903 by Henry Ford and a group of investors, the company introduced
the hugely successful Model T in 1908 and by 1923 was producing more than half
of all U.S. automotive vehicles. Through the Lincoln Motor Co. (acquired in
1922), Ford produced luxury Lincolns and Continentals. After years of declining
sales, the Model T was succeeded by the Model A in 1927; other companies such
as General Motors took the opportunity to make serious inroads into Ford's
dominance. The company was reincorporated in 1919, with Ford and his family
acquiring full ownership. Henry's son Edsel served as president 1919 – 43, and
Henry's grandson Henry Ford II led the company 1945 – 79, reviving its fortunes
considerably. Its stock was first publicly traded in 1956. Ford acquired the
British automaker Jaguar in 1989 – 90, bought the rental car company Hertz
Corp. in 1994, and purchased the automobile division of Volvo in 1999. Later
acquisitions included Aston Martin and the Land Rover brand of sport utility
vehicles. Ford also owns a significant share of the Mazda Motor Corp. Because of financial struggles at the beginning
of the 21st century, the company sold off Aston Martin in 2007 and both Jaguar
and Land Rover in 2008. Ford manufactures passenger cars, trucks, and tractors
as well as parts and accessories.
