摘　　要：随着机床不断向高精度、高刚度、高速度方向发展,对其动态性能的要求越来越高,其中机床的热性能越来越受到人们的重视,它已成为影响高速机床性能的主要因素之一。利用有限元分析软件ANSYS,在建立整机的CAD以及CAE模型基础上,实现对加工中心机床热特性的分析,以期对优化机床结构提供参考。With the continuous development of high-precision, high stiffness and high speed machine tools, the requirement of its dynamic characteristics becomes more and more high and its thermal property is attracting peoples＇ more attention. And it becomes one of the major factors which has influence on the performance of the high-speed machine tools. This paper introduces a thermal finite element analysis which is made on the foundation of CAD and CAE model of machining center machine tool by using ANSYS system. This research aims to provide references for optimizing the structural design of machine tools.
