Influence of Outer Rubber Bushing Stiffness of the under Control Arm on Multi-Link Independent Suspension Performance
Multi-link independent suspension is built according to the hard point parameters of a car. According to the multi-body dynamics and Suspension Kinematics theory, with the working condition of wheel travel and braking, the suspension performance is analyzed and discussed by changing rubber bushing stiffness of under control arm. The conclusion is drawn that axial stiffness of rubber bushing has almost no effect on the suspension performance, but radical stiffness has a little effect and torsion stiffness has the biggest effect on the suspension performance of these three parameters.
