Plateau Environment And Ammunition Storage Reliability And Evaluation Method

China's ammunition storage reliability study late started, the technology is not yet ripe, but also the lack of strict regulation of ammunition life standards, and ammunition storage reliability on plateau very few. The special characteristics of the plateau climate, the impact on the reliability of munitions storage, and entirely different from the mainland, can not be applied. In particular, retiring ammunition in the plateau, no scientific basis for reference, can only be based on the authorities. If it is not storage life and discharged early, the state will cause huge economic losses to the country.if extended service, it will increase insecurity. Clearly, the reliability of munitions on the plateau is in very prominent position, it is necessary to conduct systematic research, to provide scientific basis to the ammunition stored in the plateau.In ammunition storage reliability study, using samples to estimate the value of the parameters of failure, is very tedious work. The estimation method is commonly used maximum likelihood estimation, conventional iterative algorithm convergence of the poor, the results error, the overall situation can hardly be the optimal solution. To simplify the calculations, many of the literature estimation methods, but these are all ways to improve some limitations, the accuracy is not good. we propose two improved algorithms, the algorithm is simple, stable, not strictly on the initial request, the accuracy is good.Plateau climate of ammunition storage reliability of the impact of a groping, put forward different views about ammunition storage temperature and humidity standards and on how to reduce humidity on the life of ammunition by a specific solution.This article shows a new algorithm for the exploration and the reliability of mortar shells parameters estimated seek the failure of the mortar shells ise minimum distribution, storage life is predictived is 35 years, bigger than the national standard requirements of military, but also larger than plateau forces under the 29 years of service.
