摘　　要：采用SolidWorks软件对PCF1420反击锤式破碎机转子系统进行三维建模,并对有限元仿真模态进行分析,求出前20阶固有频率和振型.通过对比分析,得知锤子和销轴对转子固有频率和振型的影响较大.对磨损改进后的转子进行了固有频率分析,得知改进后固有频率变化不大,改进可以进行.计算分析结果为破碎机转子的结构改进和优化设计提供了参考依据.A three-dimensional model of a PCF1420 hammer crusher rotor system is built with SolidWorks soft- ware, and its first 20 order frequencies and vibration modes are comparatively analyzed by finite element modal simulation. We learn that the hammer and pin have a significant impact on rotor natural frequency and vibration mode. The natural frequency of a wear transformed rotor is also analyzed. The results show that the natural frequency changes little after an improvement, and that the improvement can be performed. The computational analysis result provides a reference frame for the structure improvements and optimization design of a crusher rotor.
