Coupling of ADAMS and MSC/NASTRAN to Model and simulate Automobile Steering Wheel Shimmy

为了啬模型的准确性 ,考虑悬架柔体系统对轿车转向轮摆振过程的影响 ,采用刚弹耦合建模的方法解决转向轮摆振问题 ,即将多刚体系统动力学分析软件 (ADAMS)和有限元分析软件 (MSC/NASTRAN)相结合的方法进行建模。将汽车前悬架多刚体动力学模型的仿真结果、多柔体动力学模型的仿真结果与道路试验数据相比较 ,结果表明刚弹耦合建模的方法能更有效地研究转向轮摆振。

In order to increase models accuracy,this paper uses the method of coupling mechanical system simulation(ADAMS)and finite element analysis(MSC/NASTRAN)technologies to model and simulate autoemobile steering wheel shimmy.The result demonstrates that this method can very efficiently model and simulate the problem of steering wheel shimmy.
