The Analysis of a Formula 750 chassis

Competition Car Technology
Chassis Assignment

The chassis of a race car has a number of functions that are required of it. It must act as a framework from which major components such as the engine, suspension, steering and axles can be mounted and held together in place. The chassis must be strong enough to take suspension loadings with minimal deflection and the inertial forces of heavy components together with aerodynamic forces, braking forces and torque reaction forces. All of this to be done while combining the greatest possible torsional rigidity with minimal weight.

The Formula 750 chassis has many good design features along with a few things that I feel require modification.

The chassis is constructed of box section steel in two sizes. Inch box is used for most of the chassis but 2inch box has been used for the lower chassis members. This is very important as the lower chassis members of a vehicle are put into a lot of tension from the bending forces imposed upon them...
