摘要：
The spindle system of EDM is directly involved in the processing process, and its thermal deformation seriously affect the processing accuracy. In this paper, we can use the method of sequential coupling, which based on the software of Workbench ANSYS, to analyze the characteristics of thermal-structure coupling in the spindle system. The temperature field and thermal deformation of the spindle system have been calculated by the simulation. And the results of finite element analysis have been verified by experiments. The results show that the internal heat source of the spindle system has a serious influence on the temperature rise and thermal deformation, and the maximum thermal deformation occurred in the direction of X axis, while the thermal deformation of other direction is not significant to the thermal deformation of the spindle system. The analysis results lay the foundation for further improving the temperature field of the spindle system and reducing the thermal deformation, and it also provides a strong basis for the design of optimization and error compensation of the spindle system.
