摘　　要：以柔性体理论为基础,使用多体动力学仿真软件A D A M S和有限元分析软件A N SY S建立了3-PU S并联机构的刚柔耦合模型,对3-PU S并联机构的刚柔耦合模型和多刚体模型进行了仿真和分析。结果表明,在仿真运动开始的瞬间,刚柔耦合模型中动平台的速度、位移和铰接处的应力均有一定频率的波动现象,反映了该并联机构实际的动态特性,为并联机构的进一步的设计、优化和校核提供了依据。The rigid-flexible coupling model of the 3-PUS parallel mechanism model is established based on the basic theory of flexible bodies,the simulation for the rigid-flexible coupling model and the multi-rigid model of the 3-PUS parallel mechanism is carried out using the software ADAMS for multi-body dynamics and ANSYS for FEA .The results show that a certain frequency fluctuations of the speed and displace of the moving platform and the stress in joint occur at the beginning which correctly reflects the dynamic characteristic of the parallel mechanism of the actual and also provides the hasis for the further design, optimization and check to the parallel mechanism.
