摘　　要：在Pro/E软件中建立某型镗刀杆三维实体模型,并运用ANSYS12.0有限元分析软件对该镗刀杆系统进行静力学分析与有限元模态分析,其中静力学分析包括加载荷后X、Y、Z方向的位移及应力分析,发现Y方向应力和变形最大;在不同进给量下的位移和应力分析中,得出随着载荷增加,镗刀杆变形在允许范围内随之增加。模态分析得到该镗刀杆系统的固有频率和振型。对该镗刀杆进行结构优化,并设计实验验证改进后的效果,为实际生产加工提供了参考。The three-dimensional （3D） entity model of a type of boring bar in the software Pro/E was established. The statics analy- sis and finite element modal （FEM） of the boring bar system was done with using of the finite element analysis （FEA） software AN- SYS12. 0. Among which the statics analysis included were the analysis of shift and stress in the X, Y and Z direction after loading, it was found that deformation of the total stress in the Y direction was maximum. Also, in the analysis of shift and stress in different feeds, it was concluded that deformation of boring bar increased within the permissible range along with the increasing of load. Modal analysis was used to get the boring bar system of natural frequencies and vibration modal shapes. Structural optimization is done to this boring bar, and the effects of design improvement are verified by experiments, which will provide references for the actual production process.
