摘要
针对某高速静压电主轴系统的内部发热将影响加工精度的问题,采用有限元分析法,使用ANSYS Workbench工作平台,对静压电主轴的温度场和热变形情况进行仿真设计,最后将温度场仿真结果与实验数据进行对比,验证仿真分析的正确性。研究结果表明,当主轴转速为5000 r/min时,油冷和水冷系统温度控制为20℃时,主轴系统各个部位的温差较大,其中,前轴承发热量较大,主轴前端产生热变形,影响了高速加工的精度要求。
In view that the internal heating problem of high-speed hydrostatic spindle system will affect the machining accuracy,the temperature field and thermal deformation of the hydrostatic spindle are simulated and designed by using the finite element analysis method and the ANSYS Workbench working platform.Finally,the simulation temperature data is compared with the experimental data to verify the accuracy of the simulation analysis.The results show that when the speed of main shaft is 5000 r/min and the temperature of oil cooling and water cooling system is controlled to 20℃,the temperature difference of each part of the main shaft system is large,among which the front bearing is the one with high temperature,which causes the thermal deformation of the front end of the main shaft and affects the accuracy requirements of high-speed machining.
