摘　　要：为揭示起爆方式对炸药爆炸能量输出结构的影响,运用LS-DNYA软件对中心轴线多点起爆方式下,炸药爆炸空气冲击波的传播过程进行计算,通过对比分析全时间历程参考位置处的冲击波超压峰值,发现起爆方式对爆炸冲击波场分布的影响规律,起爆方式对装药爆炸空气冲击波超压场空间分布及量值具有显著影响,且远场位置10点起爆装药爆炸冲击波压力幅值高、分布范围广,可有效提升装药能量利用率。研究结果可为爆破战斗部起爆方式设计提供参考。In order to reveal the effects on energy output characteristics of explosive explosion in air at different initiation modes,the shock wave propagation process of explosives with different Multi-point initiation modes were simulated by LS-DYNA program.The influence law of initiation modes on the blast wave fields were obtained by comparative analysis of blast wave peak pressure at different observation positions.The results indicate that the initiation modes have great effect on the pressure field distribution and pressure amplitude.The higher pressure and wider distribution fields were found in ten-point initiation mode,which can improve the energy efficiency of the explosive charge.The results can provide a reference for the design of the initiation modes of the blasting warhead.
