摘　　要：结合机械动力学分析软件ADAMS和有限元分析软件ANSYS进行联合仿真.利用动力学仿真得到的载荷谱读入到ANSYS中,得到更为准确的结果;另一方面,考虑到实际机械系统中柔性体的影响,构建了一个刚柔耦合模型,从而可以更加真实地模拟机构的动态性能,提高了计算精度,结果表明柔性体对机构运动精度的影响不容忽视.The mechanical dynamics analysis software of ADAMS and the finite element analysis software of ANSYS are combined to co-simulate. The more actual results are obtained through importing the load spectrums achieved from dynamic simulation to the finite element software of ANSYS. On the other hand, it constructs a rigid-flexible coupling model considering the influence of flexible body in the actuat mechanical system, gets a more real simulation of the institution of the dynamic performance and improves the calculation accuracy. Results show that the influence on kinematic accuracy of the mechanism produced by flexible body can not be ignored.
