基于故障树分析的雷位误差可靠性研究

摘要

根据鱼雷雷位误差影响因素,构建雷位误差试验失败为顶事件的故障树,进行雷位误差可靠性的定性分析和定量分析,根据重要度分析计算的关键重要度,得出了各因素对雷位误差系统的影响程度,确定了系统的薄弱环节以及维修故障的顺序.通过控制这些关键部件的可靠度便能提高系统的可靠度,从而提高鱼雷雷位误差试验的可靠度.%The fault tree of torpedo position error test failure tip occurrence is established, according to factors of torpedo position error influence. The qualitative analysis and quantitative analysis on torpedo position error reliability are carried through. The probability significance is calculated based on reliability analysis. The conclusion is effect degree of torpedo position error system's factors. The system's weakness and service fault order are confirmed. The system's reliability could be improved through controlling these key parts, it will enhance torpedo position error reliability.
