摘　　要：采用SJZ-30和GSJ-15型高速扫描相机,对端面点起爆、侧边点起爆和中心点起爆方式下,HLZY-1含铝炸药水中爆炸近场冲击波传播过程进行了实验观测,通过数字化方法得到了炸药近场冲击波沿狭缝方向的扫描曲线和冲击波压力变化曲线。研究表明,起爆方式对炸药水中爆炸初始冲击波峰值压力以及近场冲击波峰值压力的衰减有重要的影响。研究结果可以为水中兵器战斗部的设计以及毁伤效能评估提供参考。The underwater explosion near field shock waves propagation process of aluminized explosive HLZY-1 were observed by SJZ-30 and GSJ-15 high speed streak cameras. The explosives were initiated at the end surface, the side and the center. The streak curves of near field shock waves were digitized, and the pressure attenuation curves of shock wave were achieved. The experimental results indicate that the initiation mode has great effect on the original magnitude and the attenuation of near field shock waves peak pressure, which can provide some reference for design of warheads of underwater weapon and the evaluation of destroy efficiency.
