Analysis of K&C of Torsion Beam Suspension based on a Vehicle Model

In this paper, through the flexible body of torsion beam established by HyperMesh is introduced into ADAMS/CAR software for simulation of suspension K&C characteristics. The influences of three factors, such as the opening angle of the beam, beam position and bush installation angle, on the K&C performance of the suspension are obtained. The analysis shows that the opening angle and position of the beam have a great influence on the K&C characteristics of the suspension, especially the change of toe angle and height of the roll center, and provides a reference for the design of the torsion beam at early stages and a direction for the suspension K&C characteristics optimization in late period.
