摘　　要：高速加工是一项十分重要的先进制造技术,为了实现高速加工,首先必须有高质量的加工中心。主轴部件是加工中心的核心部件,其刚度特性在很大程度上决定了高速加工中心的加工质量,也是影响其加工精度的重要因素。文章利用Pro/Engineer软件建立主轴单元虚拟样机模型,完成了主轴单元虚拟样机模型之后,通过Pro/Engineer与ANSYS的软件接口将Pro/Engineer中主轴零件的模型转换成AN-SYS中的有限元模型,进行主轴的刚度分析,找出了危险截面,验证了主轴单元设计方案的合理性。High speed Machining is an important advanced manufacture technology. In order to implement machining with high speed, high-class machining center is required at first and the spindle unit is the heart part of machining center. The stiffness performance is the main factor of affecting the working performance of spin- dle unit and working accuracy. In this paper, build the spindle unit of virtual prototype by means of the Pro/ Engineer software platform. Then the model of the spindle unit in Pro/E is changed as finite element model in ANASYS through the software interface between Pro/E and ANASYS, analyzed the stiffness of the spindle, find out the danger section, which proved that the design scheme for the spindle unit is rational.
