An Improved Method for Evaluating Torpedo′s Working Reliability in Sea Trial
-
摘要: 为了客观准确地评定鱼雷可靠性水平, 针对单纯采用成败型或指数型评定鱼雷实航工作可靠度的局限性, 根据鱼雷实航功能和动作程序包含成败型和指数型的实际特点, 提出了按成败型-指数型串联综合评定鱼雷实航工作可靠度的改进方法。该评定结果是试验样本量、航行总时间、任务时间、成败型和指数型故障数等因素的综合体现, 可靠性水平随任务时间变化的显著性受指数型故障的影响相对较大, 受成败型故障影响相对较小, 评定结果更客观准确, 能有效解决单纯按成败型或指数型评定鱼雷可靠性的局限性。Abstract: Aiming at the limitation in evaluating torpedo′s working reliability only by success/failure type or index number type, an improved method for objectively and accurately evaluating torpedo’s working reliability in sea trial via combination of the two types is proposed. The evaluation result is a comprehensive one concerning test sample size, total voyage time, task time, fault number of success/failure type and index number type, etc. The variation of reliability level with task time is more significantly influenced by the fault of index number type than by the fault of success/failure type. The evaluation result of the proposed method is more objective and accurate than the conventional ones.
