鱼雷实航可靠性是鱼雷性能指标的重要组成部分,是衡量鱼雷战斗力的重要标志。本文建立了基于任务过程等规则的鱼雷实航可靠性仿真模型、算法和程序,并用案例进行了验证,结果与实际相符。此模型不仅能预计、评价鱼雷设计初期的实航可靠性,还可确定影响鱼雷任务完成的关键设备,为系统改进提供依据。 The reliability of the torpedo is an important part of the torpedo performance index, which is an important indicator to measure the combat effectiveness of the torpedo. In this paper, the simulation model, algorithm and program of torpedo real reliability based on the rules of task process are established and validated with the case. The result is in line with the actual situation. This model can not only predict the actual reliability of the early design of the torpedo, but also determine the key equipment that will affect the completion of the torpedo task and provide the basis for system improvement.
