应用空腔膨胀理论建立了尖锥形、尖卵形和抛物线形三种典型头部形状动能侵彻战斗部侵彻半无限混凝土的动力学方程,并对三种典型头部形状的动能侵彻战斗部侵彻半无限混凝土进行了数值仿真计算。基于仿真计算结果对三种典型头部形状战斗部对半无限混凝土的侵彻深度和侵彻过载性能进行了对比分析,得到了三种典型头部形状对动能侵彻战斗部侵彻性能的影响规律。 Based on the theory of cavity expansion, kinetic energy of three kinds of typical head shapes such as cone, oval and paraboloid penetrating the warhead penetrating the semi - infinite concrete was established, and kinetic energy penetration of three typical head shapes Warhead penetration semi-infinite concrete numerical simulation. Based on the simulation results, the penetration depths and penetration overload capacities of three typical head shape warheads for semi-infinite concrete were compared and analyzed, and the influence of three typical head shapes on the penetration performance of kinetic energy warheads was obtained law.
