摘　　要：利用Hyperworks分析软件,对Z轴系统进行了稳定性分析。根据设计思想,利用Hyperworks软件,通过对其几何建模、网格划分、加载约束等问题研究,首先构建了Z轴系统结构模型。在此基础上,对Ф1 500 mm超精度非球面车磨复合机床Z轴系统稳定性进行了动力学分析和拓扑优化,获得了较满意的效果。The stability analysis of Z axis system of large size ultra precision machine tool is very important for ma- chine tool design. Aiming at the subject requirements, Hyperworks analysis software is used to make the stability a- nalysis of Z axis system. According to the design idea, a structural model of the Z axis system is constructed firstly based on the geometric modeling, meshing, loading constraint problems. Secondly, on the basis of the model, dy- namic stability analysis and topology optimization about Z axis system are finished and the result obtained is satis- factory, providing a theoretical basis for the design of this type machine tool.
