环锤式破碎机转子系统临界转速与不平衡响应分析

摘要

不平衡是旋转机械的主要故障之一,针对环锤式破碎机锤头磨损后产生的不平衡问题,建立转子系统三维模型,利用有限元分析软件对转子系统进行临界转速与不平衡响应分析,得到转子系统的各阶临界转速与各种不平衡状态下的响应情况,并将分析结果运用到配锤中来,为下一步进行动平衡优化研究提供了一定的依据.%Imbalance is one of the main faults of rotating machinery.In view of imbalance caused by wearing of hammer of ring hammer crusher,a 3D model of the rotor system was established.In addition,a finite element analysis sogtware was used to analyze the critical speed and imbalance response of the rotor system,and the critical speed of each order of the rotor system and response at various imbalance mode were obtained.Finally,the analysis results was applied to hammer arrangement,which offered references for further study of dynamic balance optimization.
