摘要

旨在探究双圆柱形装药水下同步爆炸冲击波载荷的分布特性与演化规律，为水中弹药协同打击模式以及战斗部构型提供理论依据与设计基础。通过水下爆炸试验并结合数值模拟方法，系统考察了双装药间距、方位角及长径比等参数对冲击波载荷的时空演化与分布影响。研究结果表明，双装药爆炸冲击波在对称面发生同步耦合显著提升了峰值压力，侧向区域出现冲击波时序耦合呈现出二次压力峰值。数值模拟进一步揭示了装药间距与长径比对载荷分布的影响规律与机制：双冲击波交汇碰撞过程可分为入射波交汇、反射稀疏波形成及稀疏波再交汇三阶段；装药间距增大会降低冲击波在对称面的耦合压力，扩大压力和冲量的径向分布范围；长径比增大会影响耦合压力的轴向分布范围，促使压力更趋向于前侧分布，对冲量分布的影响相对较小；合适的双装药间距、长径比能够调控优化载荷的空间分布范围，有利于提升对目标结构的破坏威力。研究结果可为水下武器战斗部设计与毁伤效能评估提供理论支持与工程应用参考。

Abstract

This study aims to investigate the distribution characteristics and evolution mechanisms of shock wave loads generated by the synchronous underwater explosion of doublecylindrical charges

so as to provide a theoretical basis and design foundation for collaborative ammunition strike modes and warhead configuration. Through underwater explosion experiments and numerical simulations

the effects of parameters such as charge spacing

azimuth angle

and length-to-diameter ratio on the spatiotemporal evolution of shock waves and impulse distribution were systematically examined. The results indicate that the shock waves from the doublecharges undergo synchronous superposition on the symmetry plane

significantly enhancing the peak pressure

while a secondary pressure peak appears in lateral regions due to sequential wave coupling. Numerical simulations further reveal theinfluence mechanisms of charge spacing and length-to-diameter ratio on load distribution: the interaction process of doubleshock waves can be divided into three stages—incident wave convergence

formation of reflected rarefaction waves

and re-convergence of rarefaction waves. An increase in charge spacing reduces the superimposed pressure on the symmetry plane but expands the radial distribution range of both pressure and impulse. A larger length-to-diameter ratio affects the axial distribution of coupled pressure

leading to a more forward-concentrated pressure profile

while its effect on impulse distribution is relatively minor. Appropriate charge spacing and length-to-diameter ratiocan optimally regulate the distribution range of loads to enhance the destructive power against target structures. The findings provide theoretical support and engineering
