| 摘 要： | 针对高可靠、长寿命的高价值弹药抽样问题，提出一种高价值弹药导弹寿命评估抽样方法。通过该方法研究高价值弹药导弹寿命服从Weibull分布时样本容量、贮存时间、可靠性评估精度之间的内在关系，给出揭示三者关系的数学公式。结果表明：新方法解决了单发价值高、可供试验研究的样本少、贮存年限（生产年份）不一的高价值弹药导弹可靠性试验最小样本容量问题，为科学评估其贮存寿命提供理论参考；运用新方法对贮存8 a的某型号高价值弹药进行抽样，在置信度0.9、可靠性评估精度指标0.15条件下，该批次贮存8 a的高价值弹药最小样本容量取9发。

| Abstract: | A sampling method for life evaluation of high-value ammunitions is proposed. The sampling problem of high-value ammunition with high reliability and long life is studied. The intrinsic relationship among sample size, storage time, reliability evaluation accuracy of high-value ammunition when its life-span obeys Weibull distribution is studied, and the mathematical formulas to reveal the relationship among them are given. High-value ammunition has the following characteristics: high single-shot value, fewer samples for experimental study, and different storage years (productive year). These bring a series of difficulties to its sampling. This paper solves the problem of minimum sample size of high-value ammunition in reliability test, and provides theoretical support for scientific evaluation of its storage life. The method is used to sample a certain type of high-value ammunitions stored for 8 years. The minimum sample size of this batch of high-value ammuitions stored for 8 years is 9 with the confidence of 0.9 and the reliability evaluation accuracy index of 0.15. Key |
