摘　　要：为了获得扭力梁横梁开口角度、横梁位置、衬套安装角度三个因素对于扭力梁悬架K&C性能的影响,通过Hyper Mesh软件将建立的扭力梁柔性体导入ADAMS/CAR软件中进行悬架K&C特性仿真分析,分析得到横梁开口角度及位置对与悬架的K&C特性影响较大,尤其前束角和侧倾中心高度的变化,为扭力梁前期设计提供参考,为后期悬架K&C特性优化提供了方向。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, andprovides 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.
