鱼雷研制阶段可靠性评估方法

Reliability Evaluation Method of Torpedo in Development Phase

鱼雷在研制阶段通常进行大量的系统试验,这些试验包含了许多有效的可靠性增长信息,如何充分利用这些信息来评估鱼雷在研制阶段的实航工作可靠度成为人们关注的问题。该文针对鱼雷在研制阶段收集到的各类可靠性信息特点,提出了一种综合的可靠性增长分析方法,该方法在分析不同产品在不同试验阶段的可靠性信息特点的基础上,利用不同的可靠性增长模型评估产品可靠度,再利用信息融合的方法综合评估鱼雷的工作可靠度,为评估鱼雷在研制阶段的可靠性水平提供了一种较好的途径。

Many experiments are performed on a new torpedo in its development phase, and much effective information about reli- ability growth is available. In this paper, a synthetic analysis method about reliability growth is presented based on the reliability information obtained in torpedo development phase. In the present method, each product＇s reliability is evaluated with different reliability growth model by analyzing the characteristics of reliability information of the product in different test stage, and then torpedo＇s work reliability is evaluated by using the information fusion method. This study may offer an efficient path to estimating torpedo＇s reliability in its development phase.
