Influence of Inner Rubber Bushing Stiffness of the Lateral Rod on Rear Multi-Link Suspension Performance

Abstract:

Rear multi-link suspension is built according to hard point parameters of a car. Using multi-body dynamics and suspension kinematics theory, the suspension performance were analyzed under the simulation test of parallel wheel travel, loading brake force after the inner rubber bushing stiffness of the lateral rod is changed. The conclusion is drawn that under the test of loading brake force, changing the axial and torsion stiffness of rubber bushing has no effect on the camber angle, total track and toe angle, a little effect on ride rate and wheel rate. Under the test of wheel travel, changing the axial and torsion stiffness has also no effect on the suspension performance; but the change of the radial stiffness has effect on the suspension performance, especially the ride rate and wheel rate.
