起爆方式对智能雷战斗部毁伤概率的影响

Influence of initiation ways on killing probabilities of intelligent mine warhead

为了提高智能雷对坦克目标的毁伤概率,在应用LS-DYNA有限元软件模拟智能雷多爆炸成型弹丸MEFP(multiple explosively formed penetrator)战斗部形成过程的基础上,分析了采用中心点起爆和多点起爆方式MEFP战斗部在爆轰载荷作用下的成型规律,建立了2种起爆方式下智能雷战斗部毁伤数学模型,编制了智能雷战斗部攻击坦克顶甲的仿真程序,仿真得出了2种起爆方式下智能雷战斗部的毁伤概率。结果表明:起爆方式对智能雷毁伤概率的影响与MEFP战斗部子装药设计有关。进行智能雷战斗部设计时,需要针对不同距离目标选择设计战斗部子装药的个数,并采用相对应的起爆方式,才能有效地提高智能雷毁伤概率。

To enhance the killing probabilities of intelligent mine against tank,based on the simulation on the formation of multiple explosively formed penetrator（MEFP） of intelligent mine warhead by LS-DYNA finite element software,MEFP formation rule under explosive loading adopting both the center and multile-point initiation ways were analyzed,the killing models of MEFP intelligent mines under the actions of two initiation ways were set up,the simulation programme of intelligent mines attacking tank top armor was compiled,and the killing probabilities of intelligent mines against targets in different initiation ways were obtained.Results show that the influence of initiation ways on the killing probabilities of intelligent mine warhead is correlative to the MEFP warhead design,so that suitable EFP number of the intelligent mine warhead at different target distance should be designed,and that the killing efficiency of intelligent mines will be enhanced by corresponding initiation ways.
