【 摘 要 】

According to the statistics of FSAE, teams prefer using spaceframe chassis because it is cheaper and easy to fabricate. The only disadvantage of the spaceframe chassis over a monocoque is the greater weight of spaceframe chassis. A spaceframe chassis also makes it easy to define the suspension hard points as the chassis members can be welded together according to whatever points are needed hence making its design easy. This work will be focusing on the spaceframe chassis. Analysis of different designs for the FSAE chassis based on all the design aspects including all rules and safety aspects of the car will be carried out. The analysis will be based on various conditions that the chassis may face during its use. These conditions include the roll, pitch and yaw conditions. The chassis would be analysed for frontal and side impact situations. Also, it would be made sure that all the chassis designs meet up with the optimum value of torsional stiffness. Our work aims at providing the optimum range for the torsional stiffness which can act as a guideline for other Formula student teams in the world. Also, this paper will define the parameters that need to be considered while designing, analysing, fabricating and testing the FSAE chassis.
