A study on the circumferential propagation law of the shock waves produced by the near ground dynamic explosion of cylindrical charge

  • 摘要: 战斗部复杂的末弹道参数会影响近地爆炸冲击波的周向传播规律及对目标的毁伤程度,研究柱形装药近地爆炸冲击波传播规律对精确评估毁伤效能具有重要的工程意义。基于AUTODYN-3D软件对不同末弹道参数的柱形装药近地爆炸进行了数值模拟,通过对2个方向分别建模,获得了柱形装药近地爆炸下前、后、侧3个方向的冲击波压力数据;研究了战斗部的落速、落角、爆心高度和装药长径比4个参数对柱形装药近地爆炸冲击波传播的影响规律,分析了冲击波的演化过程、峰值压力和马赫杆高度。研究结果表明:静爆时,爆心高度是影响冲击波马赫杆高度的主要因素,落角与装药长径是影响马赫杆高度方向差异的主要因素;动爆时,能够增大周向马赫杆高度,前方最显著;另外,随着动爆速度的提升,前向冲击波峰值线性增大。正交优化的结果显示,4种变量中,动爆速度对柱形装药前方峰值压力极差最大,落角对后方峰值压力极差最大,爆心高度对马赫杆高度影响最大。通过研究柱形装药近地动爆冲击波周向传播规律,表明合理的调整装药参数和近地爆炸姿态对实现某方向的最大毁伤或减小超压伤害具有借鉴意义。
