摘　　要：为了研究叠氮化铅驱动飞片的影响因素,采用钢凹法、锰铜压阻测爆压法研究了序列的发火能量、起爆药药量、隔爆元件的材料和厚度、点火药药量对序列传爆、隔爆能力的影响。结果表明:序列需同时满足最低发火能量和起爆药药量条件才能正常传爆,起爆所需的最低发火能量为3.4 mJ,叠氮化铅最小装药量4.7 mg;隔爆元件镍、硅材料的厚度在0.32~0.80 mm时,导爆药不发生爆轰反应,但产生了凹坑和烧蚀现象;点火药高度在0.25~1.25 mm时,起爆元件的爆压变化不显著。In order to study the influencing factors of the lead azide-driven flyer-type explosive train, the effects of ignition energy, primary explosive, material and thickness of explosion-proof element and ignition composition on the detonation propagation and explosion-proof ability of the explosive train were studied by steel dent test and manganin piezoresistive sensor. The results show that the explosive train needs to meet the minimum ignition energy and primary charge conditions at the same time in order to properly propagate the explosion energy. The minimum ignition energy required for initiation is 3.4 mJ, and the minimum charge of lead azide required is 4.7 mg. When the thickness of nickel and silicon materials of explosion-proof elements is 0.32~0.80 mm, the lead charge does not have detonation reaction, but pits and ablation occur;When the ignition composition height is 0.25~1.25 mm, the detonation pressure of the initiation element does not change significantly.
