摘要:
利用LS-DYNA软件对带偏角环形聚能装药射流的二次汇聚进行了数值模拟，研究了汇聚射流的质量和环形药型罩的锥角对射流汇聚性能的影响，并进行了试验验证。结果表明：带偏角环形聚能装药可提高药型罩材料转化为射流的转化率，增大射流的连续拉伸长度和头部速度，增强射流的稳定性；二次汇聚射流头部速度随着药型罩锥角的增大而减小，头部直径随着锥角的增大而增大；对于偏角为15°的药型罩，当锥角为40°时产生的汇聚射流头部空腔较小，破甲能力较好。研究结果可为环形聚能装药的工程设计提供参考。
Abstract:
The secondary aggregation process of the jet of annular shaped charge with offset angles was simulated by the finite element software LS-DYNA. Effects of the quality size of the aggregation jet and the cone angle of liners on the jet aggregation performance were analyzed and verified by experiment. Results are as follows. The annular shaped charge with offset angles can improve the conversion of liner material into jet, increase the continuous stretch length of jet and the velocity of jet tip, and improve the jet stability. As the cone angle increases, the velocity of secondary aggregation jet tip decreases and the diameter of jet tip increases. For the 15° offset angle shaped charge, smaller cavity of aggregation jet tip and better penetration effect can be generated when the cone angle is 40°. The results can provide a reference for the practical engineering design of annular shaped charge.
