以ADGM高速数控车床用电主轴为研究对象,以优化主轴的性能为目标,利用有限元分析软件ANSYS Workbench优化设计功能,对主轴的悬伸量、跨距和电机转子安装位置进行优化。对优化前后主轴的静动态特性进行对比分析,结果表明优化后主轴的径向静刚度提高了38%,1阶固有频率提高了1%,充分改善了主轴性能,并且主轴长度缩短了40 mm,减少了生产成本。
Taking the spindle of ADGM high-speed CNC lathe as the research object and optimizing the performance of the spindle, ANSYS Workbench optimization design function is used to optimize the overhang, span of the spindle and the installation position of the rotor of the motor. The static and dynamic characteristics of the main shaft before and after optimization are compared and analyzed. The results show that the optimized radial static rigidity of the main shaft is increased by 38% and the natural frequency of the first-order shaft is increased by 1%. The main shaft performance is fully improved and the main shaft length is shortened by 40 mm. Reduce production costs.
