1 1 Problem Definition
To develop a suspension system for the new FAMU-FSU Formula SAE team The new body for the formula car presents a unique challenge not encountered by previous teams at this school The front section of the car is a carbon fiber composite matrix, where an aluminum honeycomb is sandwiched between two carbon fiber sheets The challenge therein lies in the fact that we have not had previous experience in design and fabrication of metal tubing on a carbon fiber monocoque The rear end of the new FSAE car is a traditional tube-frame, for the sake of motor support This means the design of the rear end of the car will be simpler than the front
During the course of an FSAE competition a competing racecar will be subjected to a variety of performance challenges, in which the suspension of the car will be a key factor in the success of the said vehicle
