多平台鱼雷实航可靠性试验剖面设计方法

Profile Design Method of Reliability Test for Multi-Platform Launching Torpedo in Sea Trial

针对复杂作战环境下多平台鱼雷的可靠性验证和评估难点,文中提出了一种多平台使用鱼雷的实航可靠性试验剖面设计方法。该方法从鱼雷使用任务要求出发,系统梳理出管装发射、空投发射以及助飞发射等3种平台发射鱼雷的实航全过程任务剖面,综合分析了鱼雷各实航任务剖面的工作环境应力和诱发环境应力类型;进一步提出了鱼雷实航可靠性试验的环境应力分析流程,该流程结合鱼雷历史故障分析,确定了实航可靠性验证中需考虑的综合环境应力条件,并提出了将环境载荷谱转换为鱼雷实航可靠性试验剖面的方法。文中所提方法可有效指导鱼雷实航可靠性实验验证工作,以降低湖海试验风险,同时为制定多平台使用的鱼雷可靠性试验剖面和方案提供参考。

Aiming at the challenges of reliability verification and evaluation of the multi-platform launching torpedo in complex operation environments,a sea trial reliability profile design method was proposed.Based on the mission requirements of the torpedoes,the mission profile of an entire sea trial process for three types of torpedoes,namely tube-launched,airdrop-launched,and rocket-assisted-launched torpedoes,was systematically studied.The types of working environmental and induced environmental stresses in the sea trial mission profile were also analyzed.This study further presents the environmental stress analysis process of the torpedo sea trial reliability test.Combined with a torpedo historical fault analysis,this process determines the comprehensive environmental stress conditions to be considered in the sea trial reliability verification and presents a method of converting the environmental load spectrum into a torpedo sea trial reliability test profile.The proposed method is useful for verifying the sea trial reliability of torpedoes,reducing the risk in lake and sea trials,and provides a reference for making a reliability test scheme of multi-platform launching torpedoes.
