In order to study the handling and stability of Formula SAE racing car better

based on the College Students' Formula SAE racing competition (Formula SAE racing car) of a university

it established the simulation model for the front double wishbone independent suspension system by using the mechanical system simulation software ADAMS

obtained the variation curve of kingpin inclination angle

caster

camber and toe-in four parameters by simulating and analyzing the wheels jumping

analyzed the influence of each parameter changes on the handling and stability of Formula SAE racing car

and used Insight module in ADAMS for the multi-objective optimization of the suspension system' hard point position. The results show that the motion characteristics of front double wishbone independent suspension system are effectively improved

which meets the expected design requirements of the Formula SAE racing car. This study has a certain guiding significance for the designing of the racing car suspension system.
