鱼雷贮存可靠性仿真方法

Simulation method of storage reliability for torpedo

鱼雷各舱段的贮存可靠性服从多种类型分布,传统的求解方法很难奏效,因此,采用仿真方法对其贮存可靠性进行计算是十分必要的。通过建立鱼雷可靠性模型,并根据鱼雷各舱段失效信息,分别运用Monte Carlo法与Simulink对鱼雷贮存可靠性进行仿真研究,获得鱼雷贮存可靠性各指标的点估计值与变化规律。结果表明,2种仿真方法结果基本一致,符合实际,但各有优缺点。对鱼雷贮存可靠性仿真研究,应该综合运用Mente Carlo法与Simulink仿真方法,以达到扬长避短、互为补充的目的。

For the cabins of torpedo follow multi-styles distribution,the traditional method is difficulty to solve this problem,so is necessary to take simulation method for the torpedo＇ s storage reliability computation.Based on the reliability block diagram,according to the failure message of the cabins,using the monte Carlo and simulink method for the torpedo＇s storage reliability study,obtained the point estimate and changing law.The simulation results showed that,the result of the two methods are agreed well and match the practical experience,but advantages and disadvantages existing.Simulation research on the torpedo＇ s storage reliability,we should combined use monte Carlo and Simulink method,in order to complement each other.
