Influence of Hole Size of Semi-Armor-Piercing Warhead on Ship's Cabin Implosion Effect

  • 摘要: 研究了半穿甲战斗部所造成的舱壁破孔结构对小型舰船舱室内爆效应的影响,采用LS-DYNA有限元软件对小型舰船舱室的内爆试验进行数值模拟分析,采用合理的材料本构关系与状态方程以及材料和结构连接处的失效准则,通过与等比例试验中舱内冲击波超压峰值进行对比,验证了模型的有效性。通过建立不同尺寸弹孔,分析弹孔尺寸对舱室内爆效应的影响。结果表明:破孔结构导致舱室内爆时冲击波超压峰值下降,冲击波超压峰值的出现时间延后;当弹孔直径小于舱壁长度的1/10时,导弹穿孔对舱室内爆效应所造成的影响可忽略。
