目的：评估自然贮存环境下某型控制舱贮存寿命。方法针对历年统计的控制舱成败型、不完全故障数据，假设其服从指数分布族、Weibull 分布族、极值分布族、对数正态分布族，结合工程实际处理异常数据、“倒挂”数据，采用极小 x2估计对分布函数的参数进行估计，采用极小 x2检验对各分布函数的合理性进行验证，计算“服从不同自由度下的 x2分布随机变量”检验的拟合优度。结果得到了控制舱贮存可靠性分布函数。结论通过统计的故障数据，验证了所提出数学模型评估方法的适用性和正确性，得到了在置信度为0.90、可靠度为0.95条件下控制舱的自然贮存寿命。

Objective To assess the storage life of a certain type of control cabin accelerometer in natural storage envi-ronment. Methods The historical statistics of the accelerometer's success or failure and incomplete failure data was investi-gated, assuming it was subject to exponential distribution, Weibull distribution, extreme value distribution and logarithmic normal distribution, in combination with the engineering data handling exceptions and " upside down" data, minimum x2 estimation was used to estimate the parameters of the distribution function, minimal x2 test was used to verify the rational-ity of the distribution function, and the goodness of fit of the " obeying distributed random variables under different de-grees of freedom x2" test was calculated. Results Reliability distribution function for accelerometer storage was obtained.Conclusion Through statistics of the fault data, the applicability and validity of the proposed mathematical model assess-ment methods were verified and the natural storage life of accelerometer was obtained with confidence and reliability of 0. 90 and 0. 95, respectively.
