一体化与分体式爆炸箔飞片运动形态差异性分析与性能对比OA

The structure of an integrated initiator assembly,where the flyer is directly integrated onto the surface of the bridge foil,represents one of the optimization directions for Explosive Foil(EF),and this structure can address the issue of assembly consistency in the split-type EF component.However,the differences in the motion patterns of flyer resulting from the integrated method remain unknown,and there is no experimental data to show the impact of these differences on the performance of prod-ucts,which hinders the development and optimization of integrated EF technology.Based on this,we focuse on the differences in the motion patterns of flyer between integrated and split-type EF,aiming to reveal the extent to which the differences affect performance.The motion patterns of flyer under the two structures were analyzed and their generation mechanisms were eluci-dated by using numerical simulation methods.The simulation conclusions were verified through non-charged firing experiment and an up-and-down method experiment was used to compare the working performance of the products.The research results in-dicate that the integrated structure makes flyer be cut into a flat and round shape quickly,and is less prone to cracking during its motion.The flyer collection experimental results also show that the rate complete flyer under the integrated structure can exceed 75%.The results of the up-down method experiment reveal that the minimum full-firing voltage of the integrated product is re-duced by 52 V,with the voltage standard deviation decreasing from 8.01 V to 6.08 V.This confirms that the stable motion behav-ior of the integrated flyer enhances ignition reliability.The study demonstrates the feasibility of the integrated structure and its op-timizing effect on flyer motion behavior.
