Fault tree analysis of corrosion failure for aircraft structures and improvements

  • 摘要: 对某出口用飞机铝合金结构件在热带海洋大气环境条件下服役时所发生的腐蚀失效问题,提出了采用故障树分析方法对引起飞机结构件腐蚀失效的各因素进行系统分析和探讨.根据结构件腐蚀失效过程及机理的分析,确定导致结构件腐蚀失效的各个因素,建立以结构件腐蚀失效为顶事件的故障树,通过布尔代数运算得到故障树的各阶最小割集.计算故障树顶事件的发生概率,并对底事件的概率重要度、相对概率重要度进行分析排序,找出引起铝合金结构件发生腐蚀失效的主要因素.分析结果表明飞机服役环境、阳极氧化工艺和选材是导致结构件腐蚀失效的主要因素.针对这些主要因素,提出了相应的改进防护措施.
