聚能装药用多点同步起爆网络设计

摘要

In order to improve the synchronicity and initiation capacity of multi-point explosive circuit (MEC), a “one-in-and-eight-out” multi-point synchronous initiation circuit applying for shaped charge was developed, sub-micro HMX/ DNTF melt-cast explosive was used as channel charge and JO-11C based on sub-micro HMX was also used as booster explosive. The initiation situation, booster situation, explosive-proof situation and initiation capacity of synchronous initiation circuit were studied, by the axial steel concave act of booster explosive charge, and multi-point synchronous initiation time were tested by PXI data acquisition instrument. Test results show that steel concave depth of steel piece of identification are very clear and evenly distributed after the device was initiated , the synchronous time difference is no more than 100ns,its initiation capacity is higher 7.45% than that of JO-9C booster explosive.%为提高爆炸网络的传爆同步性和起爆能力，以亚微米级 HMX/DNTF 熔铸炸药作为沟槽装药、亚微米级HMX 为基的JO-11C 传爆药作为传爆药，设计了一种聚能装药用“一入八出”式多点同步起爆网络，采用传爆药轴向钢凹法研究了多点同步起爆网络的起爆、传爆、隔爆情况和起爆能力，并应用PXI数据采集仪对多点同步起爆网络的同步时间进行了测试。结果表明：该起爆网络起爆后钢鉴定块的凹陷深度明显且均匀对称分布，同步性误差不超过100ns，起爆能力的钢凹值比JO-9C传爆药的高7.45%。
