| 摘 要： | 为了能够利用爆炸成型弹丸打击目标前的初始条件对目标内部的破片分布进行量化预测，从而可以对目标打击策略进行优化升级，采用了经过实验数据验证的数值仿真方法，对某爆炸成型弹丸垂直穿透钢板所形成的靶后破片进行了研究，分析了靶后破片的数量与所处飞散角度的关系，建立了上述关系与着靶速度（1700～1900 m/s）、靶板厚度（30 ~ 70 mm）、破片来源（爆炸成型弹丸或靶板）的联系. 结果表明:可以通过初始条件可靠地量化预测破片分布，并且靶板及爆炸成型弹丸产生的靶后破片相对累计数量随飞散角的增加而呈Weibull累积分布函数式增加.

| Abstract: | In order to predict the debris distribution in tank quantificationally by initial condition before explosively formed penetrator (EFP) attacks a target, so as to optimize and upgrade the target attack strategy, by adopting numerical simulation verified by experimental data was adopted, behind-armor debris (BAD) formed by EFP penetrating steel target was investigated, the relationship between the amount of BAD and disperse angle was analyzed, the connection between the above-mentioned relation and impact velocity (1700～1900 m/s), thickness of target (30～70 mm), the source of debris (EFP or target) was built. Results indicate that debris distribution could be predicted by initial condition quantificationally and credibly, accumulated amount of BAD generated by EFP and target increases in the manner of Weibull distribution as disperse angle increases. |
