预防性维修中鱼雷可靠度评估模型

Reliability Evaluation Model of Torpedo in Preventative Maintenance

针对鱼雷性能测试检测技术中存在的问题,基于鱼雷预防性维修实际,在马尔科夫链模型基础上建立了鱼雷可靠度评估模型,从而掌握某一预防性维修工作策略下鱼雷可靠度变化趋势,进一步论证了检验预防性维修工作策略的合理性。研究过程及模型设计能够反映鱼雷在预防性维修周期内的实际工作状况,其结果利用定量指标能够全面且系统地体现了鱼雷在预防周期内的可靠度变化,为鱼雷维修工作策略的制定提供参考。

For the shortcomings of torpedo performance test technology adopted in torpedo preventive maintenance,atorpedo reliability evaluation model is established based on the actual torpedo preventive maintenance and the Markovchain model so as to understand changing trend of torpedo reliability under certain preventive maintenance strategy.Further,the rationality of a preventive maintenance strategy is demonstrated.The research process and the design of themodel focus on the actual working conditions of a torpedo in preventive maintenance period.The quantitative resultsobtained can comprehensively and systematically describe the reliability variation of a torpedo during the period ofpreventative maintenance,and can facilitate the determination of torpedo maintenance strategy.
