The China Formula Student Car Competition has been growing in recent years. In order to improve the steering lightness and body stability of FSAE cars when driving under high-speed and multi-curve conditions. This paper constructs a three-dimensional model of suspension and steering system through CATIA according to the requirements of race rules, applies ADAMS/Car module to simulate the suspension system with two-wheel isotropic excitation, obtains the change curve of suspension performance parameters, and uses ADAMS/Insight module to optimize the unreasonable parameters through the analysis results. Based on the preliminary optimized suspension system, MATLAB is used to optimize the steering trapezoidal mechanism to make the wheel steering on both sides of the race car more closely match the ideal Ackerman geometry relationship. Finally, ANSYS is applied to finite element analysis of the important parts of the suspension and steering system to ensure that their structure and materials can meet the requirements of the whole car design.
