摘　　要：电主轴系统在多种热源作用下产生的热变形已成为影响机床加工精度的主要因素。在对电主轴系统各个生热源分析、计算的基础上,建立电主轴系统的合理模型,把计算得到的生热和传热等参数以边界条件的形式施加到有限元模型上,得到主轴系统的温度场分布和最高转速时电主轴系统的瞬态分析,计算出主轴各部分温度随时间的变化,根据分析结果提出改进措施,为完善电主轴系统的结构设计提供理论依据。Thermal deformation of motorized spindle system, which is resulted from a variety of heat sources, has become the main factors to affect the machining accuracy. On the basis of an analysis and calculations for various heat sources, we propose a resonable model for motorized spindle system, and applied the calculateded parameters （heat generation and transfer） to the model in the form of boundary conditions to obtain the distribution of temperature field and a transient analysis for the motorized spindle system at the maximum rotational speed. In this model, the temperature variations with time on spindle each sections can be calculated, and the results through the analysis provide a theoretical basis for improving the motorized spindle construction engineering.
