Method of Determination and Life Assessment for Life-Limited Parts of Torpedoes

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.
