Design and Optimization of FSAE Race Car suspension system

In this paper, FSAE race car is taken as the research object, dynamic performance of the suspension system is studied. 3D model of the whole vehicle suspension system is built by using 3D modeling software, and the kinematics simulation is carried out. On the basis of this, ADAMS is used for dynamic simulation, the changes of kingpin inclination angle, kingpin caster angle, camber angle, front wheel toe angle and ground point lateral slip amount of front wheel with wheel beat is analyzed, and the outer wheel angle has been optimized and designed. The results show that the designed suspension system meets the design requirements.
