The damage effects of fluid-filled submunition payload impacted by the kinetic kill vehicle (KKV) are investigated by simulations and ground-based experiments. Numerical simulations showed that the damage level and number of submunitions were significantly influenced by the diameter of the KKV compared with its length. Based on that, a high velocity penetrator formed by shaped charge explosion was used to simulate the direct hit experiment of a KKV impacting submunition payload. Experimental results demonstrated that the damage modes of submunitions mainly included the slight damage, perforation and total smash, showing a good agreement with the simulations. To understand the multiple damage modes of submunitions, the damage behavior of the submunitions in direct hit process were analyzed based on the AUTODYN-3D code. Numerical results presented that increased KKV diameter can increase the crater diameter and expand the damage volume, which will achieve a higher direct hit lethality. Further analysis indicated that there were other mechanical behaviors can enhance the damage to submunitions not lying in the KKV flight path, such as secondary debris kill, neighboring submunitions collision with each other, and high-speed fluid injection effect.

通过模拟和地面实验研究了受动能杀伤车辆（KKV）影响的充满液体的子弹药有效载荷的破坏效应。数值模拟表明，与长度相比，KKV 的直径对子弹药的损坏程度和数量有显着影响。在此基础上，利用聚能装药爆炸形成的高速穿甲弹，模拟了KKV撞击子弹药有效载荷的直击实验。实验结果表明，子弹药的破坏方式主要包括轻微破坏、穿孔和完全粉碎，与模拟结果吻合较好。为了解子弹药的多种毁伤模式，基于AUTODYN-3D代码分析了子弹药在直击过程中的毁伤行为。数值结果表明，增加KKV直径可以增加弹坑直径，扩大伤害体积，从而获得更高的直击杀伤力。进一步分析表明，还有其他机械行为可以增强对不在KKV飞行路径中的子弹药的伤害，例如二次碎片杀伤、相邻子弹药相互碰撞以及高速流体喷射效应。
