                  OBJECTIVES:

The objective of this project is to design, fabricate, and test a suspension system for the Formula Society of Automotive Engineers' (FSAE) racecar such that:

The suspension will fit the existing 2001 frame.

A suspension rocker and anti-roll bar will be designed which:

The cornering force is optimized.

"Squat" in the rear is limited to 1", and dive in the front to 1".

Available springs are utilized.

The A-arms, pushrods, toe links, and steer links will withstand a static cornering load of 1.5 g's.

 

The project started with an existing frame and the need for a high performance suspension.  The Suspension had to fit this existing frame as well as the various drive and upright components that had already  been designed.  
According to the above objectives the suspension system was designed.  This system consists of: upper and lower a-arms; pushrods; rockers; and toe links.  Computer software such as CAR suspension modeling and Pro/Engineer were utilized to determine spring rates, motion ratios, wheel rates, and anti-roll bar rates.  Free body diagrams were constructed and analyzed to determine loads and stresses to design individual component size.  The car has also been fitted with state of the art data acquisition in order to test and fine tune the system.
