%X 对某液体静压电主轴系统进行热态特性研究，分析系统热源和散热方式，建立基于热-结构耦合的电主轴系统有限元分析模型，通过对电主轴系统进行热-结构耦合分析，得到某工况下电主轴系统的温度场和不同方向的热变形分布。结果表明：电主轴系统的最高温度出现在主轴前轴承处；电主轴系统轴向最大热变形出现在主轴前端砂轮安装处，沿径向的热变形偏大，影响加工精度。<br>In studying the thermal characteristics of the hydrostatic motorized spindle, heat resources and heat transfer methods were analyzed. The thermo-mechanical coupling model was developed with the finite element analysis of the hydrostatic motorized spindle. The temperature distribution and thermal deformation in different directions were simulated with thermal-structure coupling analysis in a certain condition. The simulation results show that the highest temperature occurs in the front sliding bearing. The maximum axial deformation occurs in the place where the grinding wheel is installed, and the radial deformation is so large that it affects the machining precision
