为分析活性药型罩配方、炸高对混凝土靶毁伤威力影响规律，开展了活性射流作用混凝土靶侵彻与爆炸联合毁伤效应研究。采用实验和数值模拟相结合的方法，对活性射流作用混凝土靶的典型毁伤模式进行探究，给出了配方与炸高对毁伤效应的影响特性。实验结果表明：活性射流作用下，混凝土靶呈现为显著的锥形爆坑和裂纹毁伤效应；气体产物量较高配方的活性射流对混凝土靶产生更强的毁伤效应；在1倍装药直径炸高下，炸坑直径可达10倍装药直径以上。基于有限元分析软件AUTODYN-3D平台开展了活性射流对混凝土靶侵彻与爆炸行为的数值模拟，揭示了炸高对毁伤效应的影响机理：随着炸高的增大，进入侵坑内部的活性材料随之减少，活性射流对混凝土的侵彻深度呈现先增大、后减小的趋势；当炸高为1倍装药直径时，活性射流动能侵彻与爆炸反应延迟匹配较好，侵彻与爆炸联合毁伤威力较强。数值模拟结果与实验结果吻合较好。
Abstract
The penetration and damage effects of reactive material jet on concrete target are studied through experiment and simulation. The typical damage pattern of concrete target subjected to reactive jet was obtained, and the influences of formulation and stand-off distance on damage effect were studied.The experimental results show that the reactive jet produces a large conical crater and a crack zone in concrete target.The reactive liner with more gaseous products induce more violent damage on the concrete target. The produced crater diameter is over 10 times of the shaped charge diameter at a stand-off distance of 1.0D. Based on the AUTODYN-3D platform, the reactive jet against concrete target is numerically simulated to reveal the influence mechanism of the stand-off distance on the damage effect. With the increase in stand-off distance, the amount of reactive material penetrating into the crater trajectory decreases, and the penetration depth increases firstly and then decreases. The kinetic penetration time and the reaction delay time of reactive materials match well at the stand-off distance of 1.0D. Key
