2023,31(9):305-309
摘要：针对潜载鱼雷装载可靠度试验时间长、样雷数量小、验前信息少等问题，通过分析装载可靠性评估方法优缺点、装载可靠度试验鉴定主要问题，提出了实艇装载与实验室加速相结合的装载可靠度综合评估方法；结合加速试验等效原理，分析了影响鱼雷装载环境应力的主要因素，设计了装载可靠度试验总体方案和加速试验剖面，确定了恒温、温变循环、振动疲劳加速模型的试验工程化参数。算例表明，该方法解决了在较短时间内潜载鱼雷装载可靠度试验试验考核问题，在保证试验评估结论可信的同时可大幅提高试验实效，不仅可推广应用于其他类型鱼雷可靠性试验鉴定，还可指导鱼雷可靠性的研制与设计。

Comprehensive Evaluation of Torpedo Loading Reliability Based on Submarine Loading and Accelerating Test
Abstract：Aiming at the problems of long loading time, small test samples and lack pre-test informationg for submarine torpedo loading reliability, by analyzing the advantages and disadvantages of loading reliability evaluation methods and the main problems of loading reliability test, this paper proposes a comprehensive evaluation method of torpedo loading reliability based on submarine loading and laboratory acceleration. Combined with the equivalent principle of accelerated test, the main affecting factors for loading environment stress are analyzed, the overall scheme and acceleration profile of loading reliability test are designed, the engineering parameters of constant temperature, temperature vibration cycle and vibration fatigue acceleration model are determined. The example shows that, this method solves the problem of reliability test and evaluation of submarine torpedo in a short time, it can greatly improve the quality and efficiency of test while ensuring the credibility of the test evaluation conclusion, it can not only be applied to the test evaluation of other types of torpedo, but also guide the development and design of torpedo.
