Short Pulse Shock Initiation Criteria for HNS-Ⅳ Explosive

  • 摘要: 飞片冲击起爆HNS-Ⅳ炸药是直列式传爆序列的重要研究方向。考虑到能量加载方式(一般为电爆炸驱动、微装药驱动和激光驱动)和飞片材料对冲击起爆的影响, 根据文献测量的飞片阈值速度拟合得到了HNS-Ⅳ炸药pnτ和James判据的系数。同时, 利用ANSYS/LS-DYNA程序模拟了铜叠氮化物爆炸驱动飞片冲击起爆HNS-Ⅳ炸药的过程, 并根据数值模拟结果修正了HNS-Ⅳ炸药pnτ和James判据的系数。结果表明, HNS-Ⅳ炸药的pnτ(其中p为压力, τ为脉冲作用时间)判据应该调整为p2.08τ>1.54 GPa2.08·μs(0.001 μs< τ < 0.14 μs, 3.8 GPa <p < 28.0 GPa), James判据应调整为0.215/Σ+0.108/E<1(Σ为比动能, E为能通量)。调整后的起爆判据与数值模拟结果相一致, 并具有更高的实用性。
