The performance and kinetic characteristic of a suspension are closely related to the handling stability, comfort ability, and handling of the steering of a Formula SAE car. We build and analyse a simulation model of a double wishbone front suspension based on multi-body dynamics and suspension kinematic theory. From the correlation theory, the correlation of the hardpoints of the suspension is studied and discussed. From all the tests conducted, variations in the wheel alignment parameter are obtained. The optimal suspension is designed and analysed using the correlation of the hardpoints. The rational design of the hardpoints can provide a useful reference for vehicle design.
