摘要

以自扇冷却高速电主轴为研究对象,分别采用解析法和计算流体力学(CFD)方法对电主轴冷却风扇的工作风量进行计算和对比分析,同时研究了叶片数量、叶片型式对风量和风压的影响,并在此基础上对风扇叶片进行了优化设计。结果表明:采用计算流体力学方法获得的风量与解析法计算得到的结果基本一致;叶片数在9扇叶时该风扇具有较好的性能;径向式叶片能提供更大的风压,但其风量不一定更大,风量与风压中的静压有关,静压值越大,风量越大;改进后的风扇与原型相比,性能更加优良,风量提升了23.6%。
        The analytic method and computational fluid dynamics(CFD) simulations are employed in calculating and comparative analysis on flow of the fan based on fan-cooled high speed motorized spindle. The influence of blade number and blade type on cooling air volume and total pressure was studied, and an improvement design scheme was proposed. The results show that the cooling air volume confirmed by the CFD simulations agrees with the one obtained by analytic method. The fan has good performance in 9 blades. The radial blade can provide higher total pressure, but its cooling air volume may not be larger. The cooling air volume is related to the static pressure in the total pressure, and the larger the static pressure value, the larger is the cooling air volume. The improved fan is better in performance compared to the prototype, and the air volume is increased by 23.6%.
