摘　　要：针对高档数控机床热变形严重影响加工精度和加工产品质量的问题,首先介绍了高速电主轴的特点。其次,选取了某一种型号的电主轴和支撑结构,计算出热参数。再次,运用ANSYS有限元软件对电主轴单元的温度场进行了稳态和瞬态仿真。最后,根据仿真结果,提出了改善电主轴温度场分布不均匀的措施以及减小电主轴热变形的方案,为机床和加工中心等装备实现高速、高精密加工提供了一定的技术依据。To solve the problems that the thermal deformation of the high-grade CNC machine tool has much effect on accuracy and quality of the products,this paper firstly introduces the structure characteristics of the high-speed motorized spindle.Then one type of motorized spindle and supporting structure is selected,and the thermal boundary parameters are calculated.Much more the static and transient temperature field are simulated by using FEA software ANSYS in one working condition.At last,the main measures to improve the uneven temperature field and the plans to reduce the thermal deformation are put forward,which provides some technical bases for the equipment to achieve the high-speed and high-precision machining.
