摘　　要：针对冲击片雷管缺乏可靠性量化设计方法的问题,开展了冲击片雷管四点阵列输出界面可靠性设计方法研究。首先基于应力-强度干涉模型提出考虑双裕度系数的可靠性量化设计方法,构建输出性能参数与可靠度指标之间的量化模型;然后对不同设计参数下的输出性能进行仿真,建立输出性能参数与结构设计参数之间的量化模型;最后结合上述两类量化模型,给出了满足冲击片雷管四点阵列输出界面作用可靠度指标要求的结构设计参数。结果表明,该方法可以有效提高冲击片雷管输出界面的可靠性设计精度,实现精确设计。Aiming at the lack of reliability quantitative design method of the Exploding Foil Initiator(EFI),the reliability design method for the Four-point Array output interface of EFI is studied.Firstly,based on the Stress-strength interference model,the re-liability quantitative design method considering double margin coefficients is proposed,and the quantitative model between out-put performance parameters and reliability index is constructed.Then,the output performance of the output interface on differ-ent design parameters is simulated,and the quantitative models between the output performance parameters and structural de-sign parameters is established.Finally,combined with the above two types of quantitative models,the structural parameters that meet the requirements of the output interface reliability design index of the four-point array slapper detonator are given.The re-sults show that the method can effectively improve the reliability design accuracy of EFI’s output interface and then achieve accu-rate design.
