摘要
采用三维数值计算程序模拟了全尺寸钻地弹对半无限厚高强度混凝土靶板的垂直侵彻过程。根据计算结果,分析了弹-靶的动态响应特性,研究了战斗部着速对侵彻深度的影响,并分析了侵彻过程中战斗部装药的过载变化规律,得出了具有一定应用价值的结论。
Numerical simulation of the process of a full-scale EPW vertically penetrating into the semi-infinite high strength concrete target with various impact velocities was performed by the finite element code LS-DYNA. The dynamic response characteristics of the EPW and the target were analyzed. The relationship between the penetration depth and the impact velocity and the overload circumstance of the explosive charge of the EPW was studied.
