摘要

摘要: 为确保战时鱼雷的高可用性和高成功性, 迫切需要针对维修保障中的有寿件划分及寿命评估开展研究。针对多平台使用特点的鱼雷, 文中以可靠性为中心的维修为理论基础, 分析了鱼雷不同阶段的环境应力类型, 提出了鱼雷的有寿件确定原则及寿命表征参数的选取原则, 并以此为基础, 详细开展了不同分布下的寿命特征函数研究。同时, 基于鱼雷不同寿命数据, 提出了有寿件的评估方法, 并给出了实际应用案例, 为后续制定科学合理的鱼雷维修保障方案提供技术支撑。

Abstract: In order to ensure the high availability and high success of torpedoes in war, it is urgent to carry out research on the division and life assessment of life-limited parts in maintenance support. In view of torpedoes suitable for multiple platforms, based on the reliability-centered maintenance(RCM) theory, the environmental stress of torpedoes at different stages was analyzed. The determination principle and selection principle of life characterization parameters of life-limited parts of torpedoes were proposed. On this basis, the life characteristic functions under different distributions were studied in detail. At the same time, the assessment method of life-limited parts was proposed according to different life data of torpedoes, and a practical application case was given, which provided technical support for the subsequent formulation of scientific and reasonable maintenance support schemes for torpedoes.
