摘    要:为解决评估高价值、高可靠性要求火工品试验周期长、费用高的问题,提出一种基于试验信息熵等值原理的火工品可靠性评估方法,解决了GJB376所需的样本量过大和GJB377评估结果缺乏验证的问题。应用该方法能以300发以下的样本量实现对0.999可靠度要求的火工品的可靠性评估,实际产品的验证试验表明其评估结果与大样本方法相符,证明应用本方法是可行的。

关 键 词:军事化学与烟火技术  火工品  可靠性  试验信息熵

Abstract:A new method,based on test information entropy equivalence,for assessing reliability of initiating devices is presented. The method can be used to solve the problems which exist in GJB376 and GJB377. Less than 300 products are sufficient for estimating reliability of 0.999 by this new method and the result is consistent with that of the large sample assessment method. The verification test shows the method is suitable for reliability assessment of iniating devices.
Keywords:military chemistry and pyrotechnics technique  initiating device  reliability  test information entropy
