摘　　要：引信正向设计中极限边界条件的准确把握是引信安全性的有力保障,引信的环境激励、起爆控制器件等安全裕度直接关系引信安全性。针对以上问题,提出了引信安全裕度的内涵,构建了引信电磁环境安全裕度分析评估方法,主要包括已知电磁环境允许响应值、瞬态或脉冲电磁环境两种条件下的电压、电流及能量等安全裕度的计算方法。同时,重点阐述了引信起爆控制电路的安全裕度试验原则、测试点选用原则及器件参数选取等方法,为引信安全裕度理论分析与工程应用提供参考与支撑。Accurate determination of extreme boundary conditions in the forward design of a fuse is a robust guarantee for its safety.The safety margins hold paramount significance in the fuze forward design,where environmental excitations,detonation control components,and other safety factors directly impact fuze reliability.To address these challenges,this study proposes a conceptual framework for the fuze safety margins and establishes an analytical evaluation method for the electromagnetic environment safety margins in the fuze systems.The method specifically addresses two key scenarios:(1)voltage,current,and energy safety margin calculations under known electromagnetic environments,and(2)transient/pulse electromagnetic conditions.Furthermore,the paper systematically elaborates on experimental principles for safety margin verification in fuze detonation control circuits,principles for test point selection,and methods for component parameter selection.These contributions provide references and support for the theoretical analysis and engineering application of fuse safety margins.
