摘要:本文对传爆序列破片起爆系统中施主约束、传爆通道结构及飞片和受主炸药盖片的不同材料组合进行了实验研究，并就破片和受主盖片的选择进行了定性讨论，结果认为：施主约束体应选用高强度材料，传爆通道结构宜选用先小孔后大孔的阶梯方式，破片宜选用质轻高强的脆性断裂材料，受主炸药盖片宜选用低密度材料，并得到了传爆序列中使用破片起爆具有作用距离大、输出威力大的结论。
Abstract:The structure design of initiation channel, the selection of donor’s restrain material and the accepter closure disk material in the fragment initiation system of explosive sequence is experimentally studied. The results show that, the strength of the restrain material should be high, the structure of initiation channel should be like step, the material of fragment should be light, high strength and brittle facture, and the accepter closure disk material should be low density. The fragment initiation in the explosive sequence can make long function distance and high output performance.
