摘　　要：以某乘用车厂开发的轻型轿车为研究对象,基于UG、Hypermesh、Adams/car、patran建立样车的扭转梁式悬架刚柔耦合仿真模型,分析悬架弹性运动学特性及其对操稳性的影响,并将其与对标车进行悬架弹性运动性能对比,分析研发车型悬架性能的合理性。采用Adams/Insight建立参数优化模型,并进行结构参数优化设计。结果表明,经过优化结构参数达到了设计要求。Took a light car developed by a passenger car company as the study object and built Rigid-flexible coupling suspension model nsing the softwares UG, Hyperrnesh, Adams/ear and Patran. The suspension dynamie characteristics and its effects was studied on handling stability. Comparing compliance characteristic with the stand car to analysis the rationality of the suspension design and optimize suspension structure parameters to develop its per/ormance. It shows that the optimization results meet the design requirements.
