摘　　要：对42CrMoSrIn钢新型机床主轴进行了传统PID控制和模糊-PID控制,并进行了室温磨损性能、高温磨损性能和显微组织的测试、对比和分析。结果表明:与传统PID控制相比,经模糊-PID控制后的试样室温磨损体积和高温磨损体积分别减小了29.41%、44.44%,试样的室温磨损性能和高温磨损性能均提升。模糊-PID控制的效果优于传统PID控制,可以提高机床主轴的质量。The traditional PID control and fuzzy-PID control of the spindle of 42 CrMoSrIn steel were carried out, and the wear performance at room temperature, wear performance at high temperature and microstructure were measured, compared and analyzed. The results show that compared with those of the traditional PID control, the wear volume at room temperature and the high temperature wear volume of the specimens after fuzzy PID control decrease by 29.41% and 44.44% respectively.The room temperature wear properties and high temperature wear properties of the samples are improved. The effect of fuzzy-PID control is better than that of traditional PID control, and the quality of machine tool spindle can be improved.
