摘要:
针对EFP战斗部多点同步起爆系统所使用的常规电雷管安全性低和爆炸网络同步性差的问题，基于爆炸箔起爆技术固有的高安全特性，以2发或3发冲击片雷管串联为多点起爆系统的基本单元，设计了3点、4点、6点和9点同步起爆系统，并进行了多点起爆同步性测试。试验结果表明：3点、4点同步起爆同步性时间均小于100 ns，最大同步性时间散布较小，满足设计要求；6点和9点同步起爆同步性时间都超过了100 ns，并且最大同步性时间散布较大。经分析，每组雷管之间等效电阻和等效电感等参数具有差异，造成不同组别的雷管发火回路性能有差别，故引起各起爆支路的电流不一致，导致桥箔的爆发电流和爆发电流密度的差异，从而影响起爆的同步性。
Abstract:
Due to the low safety of conventional electric detonator used in multi-point simultaneous initiation system of EFP warhead and bad synchronization of explosive network, three-point，four-point, six-point and nine-point synchronized detonation systems were designed based on high safety characteristics of explosion foil initiation (EFI) technology, and using two or three EFI in series as the basic unit. Multi-point synchronization trials were carried out. The results show less than 100 ns synchronization time and concentrated distribution of the maximum synchronization time for three-point and four-point systems, which meets the design requirements, and more than 100 ns synchronization time and dispersed distribution of the maximum synchronization time for six-point and nine-point system. According to the analysis，the difference in parameters of resistance and equivalent inductance between each group of detonators equivalent causes the variation in their detonator firing circuit performances. As a result, the affected current of each initiation branch will create difference in burst current and burst current density of bridge foil which finally affects synchronization.
