摘　　要：针对重型数控落地铣镗床主轴组件的热态特性进行分析,研究了主轴组件内部热源发热量和热边界条件的确定方法,运用有限元方法对落地铣镗床主轴组件工作过程中的温度场分布进行了建模,并用实验的方法对主轴组件的温度场分布模型进行参数修正,提高了建模精度。This article analyzes the thermal characteristic for spindle components of NC heavy duty milling-boring machine tool, es- tablishes the methods of determining the heating value of internal source and the thermal boundary conditions and builds the modet of the temperature field distribution for spindle components of milling-boring machine tool in the process of operation with finite-element methods. And then with experiment, model parameters of distribution of temperature field for spindle components are revised to im- prove the modeling accuracy.
