Analysis and Experimental Methods for Safety Margins in Fuse Electromagnetic Environment
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 safe-ty margins and establishes an analytical evaluation method for the electromagnetic environment safety mar-gins 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.
