摘　　要：起重机的电气系统是一个较复杂的系统,运行过程中出现的电气故障类型各种各样。提出应用故障模式及影响分析(简称FMEA)方法对起重机电气系统进行故障分析,首先介绍了基于FMEA的起重机电气系统故障分析方法,并给出了具体的故障分析流程;然后依据所提出的方法,分别对电气系统的组成部件、子系统及系统进行了故障模式与影响分析。获得了系统故障与各个子系统故障、各个电气部件故障之间的逻辑关系,为起重机电气系统的故障分析及运行监测、故障预报奠定了基础。Due to the complexity,crane electric systems may occur variety types of electric faults in the process of operating.In this case,firstly this article proposed a method to do fault analysis for crane electric systems applying fault modes and effects analysis(FMEA),and put forward fault analysis procedures in details.Then according to the proposed method,the paper respectively analyzed the fault modes and affections towards the electric system components,sub-systems and the entire system,by which the logical relationship among sub-systems,each electric component and the entire system have been obtained.The method establishes a foundation for operating monitoring,fault analysis and prediction for crane electric systems.
