针对某型飞机起落架的一例典型故障,根据其工作原理图,采用故障树分析法(Fault Tree Analysis,FTA)对故障进行分析、诊断,建立了以故障现象为顶事件的故障树及故障结构函数,得到了故障现象对应的所有基本事件。再结合某单位统计的此类...针对某型飞机起落架的一例典型故障,根据其工作原理图,采用故障树分析法(Fault Tree Analysis,FTA)对故障进行分析、诊断,建立了以故障现象为顶事件的故障树及故障结构函数,得到了故障现象对应的所有基本事件。再结合某单位统计的此类故障基本事件的先验概率,通过重要度计算得到了该故障现象的失效概率,制定了故障诊断流程,为该型飞机此类故障的高效诊断、分析、维护提供依据与参考。展开更多
针对某型火炮随动系统的故障数据,对火炮随动系统进行可靠性分析。采用故障模式与影响分析(failure modes and effect analysis,FMEA),通过统计存在的故障模式及原因分析,得到造成火炮随动系统故障的主要原因,提出针对性的改善措施;根据...针对某型火炮随动系统的故障数据,对火炮随动系统进行可靠性分析。采用故障模式与影响分析(failure modes and effect analysis,FMEA),通过统计存在的故障模式及原因分析,得到造成火炮随动系统故障的主要原因,提出针对性的改善措施;根据FMEA结果,建立火炮随动系统故障树,计算火炮随动系统故障的最小割集,将其分为6类,针对不同的底事件故障类别提出改善措施。结果表明:该分析可为提高火炮随动系统的可靠性提供数据支撑,为火炮随动系统的设计和预防维修提供理论依据。展开更多
为了提高某型飞机起落架故障诊断率,分别采用故障树分析法(Fault Tree Analysis,FTA)和FTA与RBF神经网络(Radial Basis Function,RBF)的方法对起落架常见故障进行诊断。首先根据起落架工作原理图,采用FTA方法建立故障树及故障结构函数,...为了提高某型飞机起落架故障诊断率,分别采用故障树分析法(Fault Tree Analysis,FTA)和FTA与RBF神经网络(Radial Basis Function,RBF)的方法对起落架常见故障进行诊断。首先根据起落架工作原理图,采用FTA方法建立故障树及故障结构函数,得到所有的最小割集,计算故障失效概率;然后按照最小割集重要度,筛选出RBF神经网络训练样本的变量数目;最后再结合国内某维修单位的故障统计数据,运用RBF神经网络建立了故障诊断模型,并对模型进行了训练和测试。结果表明,FTA定量计算得到的故障失效概率为71.60%,FTA+RBF结合方法的故障诊断平均预测误差为1.0%。展开更多
