摘要: 以COMSOL Multiphysics有限元分析软件为工具,建立170SD30-SY型电主轴水冷系统有限元模型,并对不同水流量下水冷系统温度场进行仿真;搭建水冷系统温升实验平台,分别对不同转速下的电主轴水冷却系统参数与电主轴温度的关系进行实验。研究结果表明:不同转速下,随着冷却水流量的增加,电主轴温度有不同程度的降低;冷却水流量为0.28 m3/h~0.30 m3/h时,冷却效果均为最佳选择;同时,通过改变冷却水初始温度来控制电主轴温升具有更直接效果。Abstract: With the finite element analysis software of COMSOL Multiphysics, a finite element model of water-cooling system for 170SD30-SY motorized spindle was built, and the temperature field of water-cooling system under different water flows was simulated; furthermore, a temperature experiment platform of water-cooling system was built, then the experiments were carried out respectively under different water flow speeds to validate the relationship between the cooling system parameters and temperature rise. The results showed that under different speeds, the spindle temperature was reduced in different degrees with the increase of the cooling water flow rate; and it achieved the best cooling effect when the cooling water flow rate was 0.28 m3/h~0.30 m3/h; meanwhile, it had a more direct effect to change the initial temperature of cooling water so as to control the spindle temperature rise.
