... Suspension systems can be considered as an interconnection of rigid bodies through kinematic joints or compliance elements such as rubber bushings or elastic springs (Yang et al, 2006;Park & Sohn, 2012). They play an important role in vehicle performance in terms of its handling ability, stability, and ride comfort (Yang et al, 2012;Mahmoodi-Kaleibar et al, 2013). The suspension system of a vehicle isolates it from uncomfortable vibrations transmitted from the road through the tires and transmits control forces back to the tires so that the driver can control the vehicle (Li et al, 2003;Liu et al, 2011). ...
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.
