摘要: 考虑了炸药在水介质中爆炸时不同深度水压会对爆炸参数产生不同的影响, 该文采用有限元软件ANSYS /LSDYNA建立了典型装药在不同水深压力下爆炸的仿真模型, 计算了在不同水深压力下不同点处的爆炸冲击波压力, 分析了炸药水中爆炸的冲击波压力随水深的变化关系, 得出了同一装药在不同水深处爆炸时, 与爆心不同相对位置处的冲击波压力随水深的变化规律。本文的研究有助于水中兵器战斗部毁伤威力的评定以及引信作用距离的设计。Abstract: When a charge explodes in water, differentwater pressure exerts different in fluences on the explosive parameters. Using the finite element analysis software ANSYS/LS-DYNA, a simulation model of a typical charge explosion under different water pressure is established. The blastwave pressure at different points under different water pressure is calculated, and the blastwave pressure changing with water pressure is analyzed. The basic law of the in fluence of water depth on blastwave pressure is concluded. This research will be valuab le to these fields, such as the assessment of warhead lethality of underwater weapons, and the design of fuze range, etc.
