| 目的 针对导弹战斗部装药恒定应力加速寿命试验数据，开展装药贮存寿命评定研究。方法 采用装药样品在61、71、81 ℃等3个温度下的加速老化数据，以样品质量损失率达到临界质量损失率为装药失效依据，评定装药贮存寿命。根据装药加速寿命试验数据特点，优选平方根模型、线性模型、逆威布尔模型、幂函数模型和乘方模型等5种模型对装药质量损失率的数据进行拟合，采用拟合优度和工程实际相结合的方法，确定合理的分布函数，评定战斗部装药贮存寿命。结果 编制计算程序对某导弹战斗部装药加速寿命试验数据进行了处理，根据拟合优度和工程实际，认为乘方模型(0.9方，呈近线性)最佳，评定装药贮存寿命为22 a。结论 通过加速试验数据得出某导弹战斗部装药贮存寿命符合新引入的近线性模型，优于平方根模型和线性模型。 |

| The work aims to study the evaluation of charge storage life based on the constant stress accelerated life test data of certain missile warhead charge. The accelerated aging data of the charge samples at 61 ℃, 71 ℃ and 81 ℃ were used to evaluate the storage life of the charge based on the critical weight loss rate of the sample. Five models including the square root model, the linear model, the inverse Weibull model, the power function model and the power model were chosen to fit the weight loss data of charge according to the characteristics of accelerated life test data. The rational distribution function was determined combining the goodness of fit and the engineering practice, so as to assess the storage life of the warhead charge. A calculation program was prepared to process the accelerated life test data of certain missile warhead charge. The power model (0.9 square, near-linear) was considered optimum by the goodness of fit and the engineering practice. The assessed storage life of the charge was 22 years. It is concluded that the storage life of certain missile warhead charge conforms to the newly introduced near-linear model, which is better than the square root model and the linear model. |
