摘　　要：针对火工品的高发火可靠性指标(可靠度下限p,置信水平1-α),基于估计100%p发火点的小样本优化试验设计,给出100%p发火点的置信上限、鉴定火工品可靠性的方法以及火工品作用裕度的区间估计。模拟研究表明,利用优化试验设计估计火工品的100%p发火点,样本量小,精确度高;利用优化试验设计鉴定火工品的发火可靠性,样本量小、结果可信且略显保守。Aiming at the requirement in the initiator＇s firing reliability,the upper limit of 100% p firing level and the confidence interval of the function margin were given on basis of an optimal experiment design for estimating 100% p firing level.Then,a qualification method for the firing reliability of initiator was provided.Simulation study shows that,based on the optimal experiment design with small sample size,the estimation of 100% p firing level is precise and the result of reliability qualification is reliable but conservative a little bit.
