摘要
为了分析电主轴150MD24Z7.5水冷系统对其电机的冷却功效,采用有限元软件建立流固耦合传热模型,数值模拟分析了水流速度对电机的冷却效果。模拟分析发现,当流速相对较小时,流速的改变对电主轴的冷却效果的影响较大,但随流速继续增大,对电主轴冷却效果的影响逐渐减小直至饱和。针对仿真结果进行试验验证,试验结果与仿真结果相符。从而为电主轴冷却参数优化提供了理论基础,满足电主轴电机冷却的技术要求。
In order to analyze the cooling function of the water cooling system on the 150MD24Z7. 5 motor-ized spindle, a fluid-solid coupling heat transfer model established in finite element software and numerical simulation analyzes the cooling water velocity effect on the motor of the motorized spindle. Simulation results shows that when the cooling water velocity was relatively small, it has a great influence with the velocity changed on the cooling effect and with the flow velocity increased , the difference in cooling effect was inappreciable . Experiments were conducted according to the results of theSimulation analysis and the experimental temperature is consistent with simulation results. Consequently, an theoretical basis is offered for the parameter optimization of motorized spindle cooling system which can meet the requirementsof high-speed spindle motor cooling technology.
