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。
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.
