摘　　要：采用爆炸动力学程序Object-MMIC数值模拟了FAE爆炸超压场的时空分布,分析了针对有生力量的冲击波毁伤半径及面积的变化规律。研究表明:云爆超压场可分为三个区,由爆炸中心向外分别为云雾爆轰直接作用区、爆轰产物和冲击波联合作用区及冲击波作用区;云爆冲击波的毁伤面积随固定云爆体积内总能量线性增加。The space-time distribution of FAE detonation overpressure field is simulated by means of Object-MMIC, a dynamic program, in this paper. The changing pattern of damage radius and area of shock wave with effectivity are analyzed. It is found that the overpressure field can be divided into three subareas, namely, the direct action area of cloud detonation, the united action area of the detonation outcome and the shock wave, the shock wave action area. The damage area of cloud detonation shock wave increases linearly with the total energy of cloud detonation.
