摘　　要：基于有限元思想,运用ANSYS软件建立了轴与轴座的三维模型。采用MPC技术实现了两者的装配,对装配体进行了模态分析,并与粘接和一体化结构的模态分析结果进行了比较。研究结果对复杂装配体的模态分析和动力学分析具有一定的指导意义。The 3-D model of axle and axle bed was established through the ANSYS software based on finite element theory~ By using MPC method, the assembled parts was connected and the mode analysis was carried out o The results are compared with these of a corresponding bonding and intergrative structure and provide a guidance for the mode analysis and dynamic analysis of the complex assembly structures.

关 键 词：有限元 ANSYS 装配体:模态分析
