摘　　要：利用CAE工程分析软件Pro/E对3-TPS并联机床的主体结构进行了线性静态有限元分析,该机床在某一工作位置的三种不同受力情况下的刚度和应力分布情况,分析结果与实际情况基本吻合,为机床的局部改进和后续优化提供了依据。The linear static finite element analysis for the main structure of 3 - TPS parallel kinematical machine tool was carfled out with Pro/E, a CAE engineering analysis software, and the distributions of stiffness and stress of this machine at a working position under three kinds of stress were obtained. The result accords to the actual situation and provides a basis for improving part of the machine tool and subsequent optimizing.
