摘　　要：提出一种能同时满足火工品发火可靠性和安全可靠性的设计方法,把火工品可靠性指标转换成感度分布参数的取值范围,通过对感度的调节使产品满足发火可靠性和安全可靠性要求,为火工品可靠性设计提供了一条新思路。推导出了常见火工品感度在正态分布、逻辑斯谛分布、对数正态分布和对数逻辑斯谛分布等常见分布条件下把可靠性指标转换为感度分布参数的表达式,实例证明这种方法对火工品研制有指导作用。A sensitivity parameter design method for reliability of explosive initiators is presented. To meet the requirements of fire reliability and safety reliability, the reliability index is transformed to sensitivity distribution parameter and it may control reliability of explosive initiator by modulating sensitivity during its development. The mathematical expressions about reliability index and parameter of sensitivity distribution of explosive initiator with Normal distribution, Logistics distribution, LogNormal distribution and LogLogistics distribution are deduced. An application example shows that it is instructive for development of explosive initiators.
