为探究空腔装药在水下爆炸中冲击波传播特性及能量分布情况，实现载荷轴向定向增强。采用AUTODYN软件建立对称欧拉数值模型，模拟不同空腔半径与装药半径比例下的空腔装药水下爆炸过程，分析空腔装药冲击波传播规律以及等体积、等质量条件下轴向压力峰值和比冲量变化，结果表明合理选择空腔尺寸可在特定距离范围内显著提升轴向压力和比冲量，可以实现载荷定向调控。该研究可为设计具有增强近场毁伤效能的水下武器战斗部作出贡献。
In order to investigate the cavity charge in the underwater explosion shock wave propagation characteristics and energy distribution, to realize the load axial directional enhancement. The use of AUTODYN software to establish a symmetric Euler numerical model, simulate different cavity radius and charge radius ratio under the cavity charge underwater explosion process, to analyze the cavity charge shock wave propagation law and equal volume, equal mass conditions under the peak axial pressure and specific impulse changes, the results show that a reasonable choice of the cavity size can be a significant enhancement of the axial pressure and specific impulse within a specific distance range can be realized load loading directional The results show that the axial pressure and specific impulse can be significantly enhanced by choosing a reasonable cavity size in a specific distance range, which can realize the directional load regulation. This study contributes to the design of underwater weapon combatants with enhanced near-field damage effectiveness.
