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.
