In order to effectively evaluate the reliability index of in-service torpedo, combined with the actual use of torpedo, the reliability evaluation method of in-service torpedo based on conditional reliability is proposed. On the basis of determining the failure distribution under the single state of components, the variation of the reliability distribution of the components after several states are studied. Based on the fault tree structure function, the reliability simulation model of torpedo is established, and the Monte Carlo method is used to establish the simulation solution process, so as to obtain the reliability parameters of torpedo. This method is simple and easy to implement, and has important guiding significance for evaluating the reliability of in-service torpedoes.
