摘　　要：根据迷宫式往复压缩机活塞杆在活塞运动的方向通过导向轴承支承的特点,建立活塞杆力学简化模型,利用ANSYS软件对活塞杆进行模态分析、谐响应分析和屈曲分析,确定相关参数对活塞杆振动和稳定性的影响,最终实现活塞杆导向支承的优化。The piston rod of labyrinth reciprocating compressors is supported bv a guide bearing system in the direclion of movement. According 1o such configuration, a simplified mechanical model of piston rod is eslablished. To determine effect of relevan parameters on the vibration and stability of piston rod, modal analysis, harmonic： analysis and buckling analysis are performed with ANSYS software, and considering the result of which the optimization of guide support system of piston rod is achieved.
