摘　　要：终点效应是毁伤效能分析中的重要环节,为准确评估制导杀爆弹的毁伤效能,基于LS-DYNA有限元分析平台开展了终点效应数值模拟研究。构建了战斗部装药和预制破片的三维模型,采用一端点起爆方式模拟空爆。通过数值模拟计算研究了制导杀爆弹破片场分布和冲击波压力场分布,分析了不同距离处钢结构靶板在毁伤元作用下的失效过程,发现了制导杀爆弹爆炸后冲击波与破片分离的时间与位置,以及破片场分布的基本规律,为后续开展制导杀爆弹毁伤效能数值模拟研究提供数据参考。Terminal effect is crucial part in the analysis of damage effectiveness.To accurately evaluate the damage efficiency of guided killing explosive bomb,numerical simulation of terminal effect was carried out based on the LS-DYNA finite element analysis platform.A three-dimensional model of warhead charge and prefabricated fragmentation was constructed,and an end-point detonation method was used to simulate air-burst.The distribution of the fragment field and the pressure field distribution of the shock wave are investigated through numerical simulation and calculation.The failure process of the steel structure target plate under the action of the destructive element at different distances is analyzed,and the time and position of the separation of the shock wave and the fragment after the explosion were found,as well as the basic law of the fragment field.It provides a data reference for the subsequent numerical simulation of the damage efficiency of the guided killing explosive bomb.
