摘　　要：针对多段离散杆战斗部各段杆环间隙大的问题,提出了一种新型双层离散杆战斗部结构,利用非线性有限元软件进行了爆炸载荷下双层离散杆战斗部杆条飞散过程的数值模拟分析。研究结果表明,新型双层离散杆战斗部能够形成两个相互交叉且独立的杀伤环,可对目标产生网状切割作用及二次毁伤,有效提高对目标关键部位的杀伤密度及毁伤概率。A new double-deck discrete rod warhead was proposed for the problem of the multi-stage discrete rod warheads.A nonlinear finite element software was used to complete the numerical simulation of the double-deck discrete rod deploying under explosion load,and the simulation results were analyzed.The results show that the new double-deck discrete rod warhead can form two inter-digitated and independent killer rings,which can produce mesh cutting and secondary damage to the target,so the killing density and the probability of damage on key parts of targets can effectively be improved.
