Influence of Coupled Macroscopic Deviation of Shaped Charge on Lateral Displacement of Jet

  • 摘要: 聚能装药宏观偏差是引发射流横向偏移的原因之一,为研究多种宏观偏差对射流横向偏移的影响规律,根据射流成形理论推导了同轴度偏差、壁厚偏差和位置偏差对射流横向偏移量的影响的理论分析模型。对存在多种宏观偏差的聚能装药采用数值模拟方法开展射流形成过程的计算,获得了各类宏观偏差对射流横向偏移量的影响规律。结果表明,单一的同轴度偏差和位置偏差均导致射流呈二次曲线状,单一的壁厚偏差使射流偏转,但射流仍保持直线状。在多种宏观偏差相互耦合的情况下,射流横向偏移量约为各单一因素引起的偏移量的矢量和。研究成果可为提高聚能装药的稳定性提供参考。
