摘要: 由于鱼雷产品的可靠性不断提高,同时可靠性试验受经费、时间等因素的限制,导致鱼雷实航工作可靠度的评定面临现场试验数据不足的问题。近年来,普遍采用补充可靠性先验数据结合Bayes方法进行综合评定来解决这一小子样问题。针对现有先验数据获取未能充分利用性能可靠性信息,利用Bootstrap仿真方法对性能可靠性数据进行仿真增加样本量,作为现场可靠性Bayes评定的先验数据,极大地降低了实航工作可靠度评定样本不足对评估结果的影响,具有很好的工程应用价值。

Abstract: Torpedo working reliability assessment comes up against the condition of lacking sample, because of increasingly long lifetime and restricted reliability test by expenditure. In recent years, technical experts usually mine prior data combined with reliability test data to solve the problem using Bayes method. Considering that the existing prior data acquiring doesn't cover the performance reliability information, the Bootstrap simulation method is used to obtain the performance data as the prior data utilized by Bayes reliability method, which tremendously relieves the influence of lacking prior information on reliability assessment and has practical engineering value.

Key words: Bootstrap, working reliability assessment, performance reliability, priori data, reliability assessment, Bayes method
