摘要
简单介绍利用模态综合方法建立刚体、弹性体耦合系统的一般理论.使用MSCNastran和MSCAdams/Car软件建立某轿车的整车刚弹耦合系统模型,进行整车匀速直线行驶工况下的仿真,计算得到车身的振动响应和车身、底盘连接点处的传递力,并讨论整车刚弹耦合模型的正确性.
The common theory of building rigid-elastic coupling model with component mode synthesis method is introduced simply. The rigid-elastic coupling model of a car is built by using MSC Nastran and MSC Adams/Car. The simulation in even speed straight driving for full-vehicle model is carried out. The vibration response of body and transfer force between body and chassis are calculated, and the validity of rigid-elastic coupling model is discussed,
