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 u-sing 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 distri-bution 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.关键词
