变锥角聚能装药水中爆炸数值模拟研究

摘要

For improving the damage effect to underwater target of warhead, a kind of metamorphic tapered angle shaped charge is designed, and the damage mechanism is analyzed. The physics model of tapered and spherical shaped charge under underwater explosion is build, numerical simulation is done by LS—DYNA, and the stress distribution is got. The result shows that the shaped charge jet formed by this structure can provide movement space for latter EFP,which improving the damage effect to target.%为提高战斗部对水下目标的破坏作用,对一种变锥角聚能装药进行了结构设计,并分析了其破坏机理.建立了圆锥、球缺组合式变锥角聚能装药水中爆炸的力学物理模型,并利用大型有限元软件LS-DY-NA进行数值模拟计算,得出了其应力场分布.研究结果表明该结构产生的聚能射流能为后续EFP弹丸随进破坏提供运动空间,增强了对目标的破坏效应.
