以液压挖掘机试验台动力系统为研究对象,采用系统失效模式及后果分析方法(Failure Modeand Effects Analysis,FMEA),确定液压挖掘机试验台动力系统的关键部件,再运用组件失效模式及后果分析方法判断各部件的主导故障,制定相应的故障停机率降低策略,并通过实例来进一步说明。 Taking the hydraulic excavator test-bed dynamical system as the research object, the key components of hydraulic excavator test-bed dynamic system are determined by the system failure mode and the result analysis method (FMEA), and then the component failure mode and the consequence analysis method Determine the leading failure of each component to develop a corresponding strategy to reduce the downtime rate, and further examples to illustrate.
