一种鱼雷武器服役期间实航可靠度评定方法

An Assessment Method of Sea Trial Reliability for Torpedo in Commission

针对鱼雷武器服役期间实航可靠度评估存在子样少,不利于做出准确评估这一实际情况,在分析鱼雷年度实航数据的基础上,提出了一种把不同批次鱼雷与不同服役年限实航数据综合起来进行评估的方法。通过对不同批次与不同服役年限鱼雷实航信息进行母体检验,合理的扩大了实航样本量,提高了评估精度与可信度。实例计算表明该方法简单实用,满足工程实际需要。

The existing assessment of torpedo working reliability in sea trial is not accurate because of insufficient sample, an assessment method by combing the sea trial data of different batches of torpedoes with different service life is presented through analyzing annual torpedo sea trial data. Through the population inspection, the sample size is ra- tionally expanded, and the information for reliability assessment is increased. Thus, the precision of reliability assessment is improved. The example shows that the proposed method is convenient for engineering application.
