| 摘 要： | 为了提高发动机曲柄连杆机构的可靠度,采用FTA-FMMEA综合分析法对其进行分析。通过分析曲柄连杆机构各零件的故障,建立故障树模型,对其进行定性分析找出对系统影响较大的故障模式;对其中的活塞环磨损这一故障模式进行FMMEA分析,得到了其故障原因及故障机理,确定了其故障影响,并根据分析结果提出改进方案。改进前后的RPN值对比结果表明,FTA-FMMEA综合分析方法可以很好的分析系统故障并提高系统可靠性水平。

| Abstract: | FTA-FMMEA comprehensive analysis method can be used to improve the reliability of engine crank rod system.The analysis process can be described as follows: firstly,establish the fault tree model based on the analysis of the part failures of the crank rod system,and find the hazardous failure mode according to FTA qualitative analysis;then analyze the mode scuffing of the piston ring by using FMMEA,get the failure cause and failure mechanism,find the failure effect,and finally give the correction measures ac... |
