Topology Optimization and Analysis of Racing Car Chassis Based on FSAE Rules
The chassis of a Formula Student racing car serves as the foundation for the entire vehicle's as-sembly,and its strength and stiffness directly impact the vehicle's fuel economy,power performance,and maneuver stability.Based on the rules of FSAE,a three-dimensional model of the chassis was created in CATIA software.Leveraging the results of topology optimization,the initial chassis model was refined within CATIA.An analysis of the chassis'deformation and stress under various operating conditions was conducted to assess whether its strength and stiffness met the competition's requirements.Additionally,a modal analysis was performed to prevent resonance during racing.The simulation results of the optimized chassis indicate that both its strength and stiffness meet the standards set by the FSAE.As a result by par-ticipating in the FSAE in the 2021 and 2022 seasons,the designed chassis successfully meets the competi-tion's requirements.
