Abstract
In order to improve the handling of the suspension system in FSC racing cars under extreme operating conditions, the overall strength stiffness of the car is improved to provide reliable support and protection for the driver, engine and all other components. This paper focuses on the torsional stiffness of the load bearing members required for the transient conditions of the car entering and exiting the corners. Based on the design value, 3D modeling was carried out according to the 95th percentile manikin and driver data. Importing Hypermesh to divide the mesh for finite element analysis of each working condition, and changing the skin thickness, core material thickness or core material type for each area of the whole vehicle to continue to optimize the performance of the parts and complete the purpose of lightweighting.
