基于根原因分析法的飞机连接器熔损故障分析

The connectors melting fault analysis based on root cause analysis

以连接器熔损故障事件为案例,应用根原因分析法进行失效分析,展示了其应用的整个过程,解释了根原因到达顶事件的路径及失效机理。通过完整记录所有收集的证据和调查中所采用的行动,极大地增加了确定导致顶事件发生的真正根原因的机会,并提供了不会导致顶事件发生而终止的解释。对导致顶事件发生的所有可能原因进行全面调查,提高了对调查过程的认识,并且可将所获得的技术应用于相关的设计中,防止同类事件再次发生。

Taking the connector melting failure event as an example,it uses root cause analysis for failure analysis,determines the root cause and describes the failure mechanism. It obtains a full record of all evidence and action as part of the investigation greatly,increases the chance that the true root causes of the failure and provides the rationale for closure of non- contributing cause of the failure. Based on investigation of all possible causes of the failure,it improves the identification of areas for process. This method can incorporate into related design to prevent the occurrence of the similar event again.
