摘　　要：通过理论分析和仿真计算研究金属加速炸药/高爆热炸药复合装药的能量输出特性,以及对破片驱动和冲击波超压性能的影响;选择3种炸药组成复合装药结构,制备全预制破片战斗部样弹,采用试验方法验证复合装药的破片驱动能力和冲击波超压特性,并与金属加速炸药单一装药进行比较。结果表明,理论分析及仿真计算与试验结果吻合较好,复合装药的爆速及爆热值在组成复合装药的炸药的极限参数之间;通过复合装药配比调整可以达到破片与冲击波超压综合能量最佳匹配,可应用于杀爆战斗部优化设计。Energy output characteristics of composite charge, as well as the influence to fragment and shock wave overpressure were studied by theoretical analysis and simulation calculation. Fragmentation warheads were made with three kinds of explosive composite charge structure, fragment driving capability and shock wave overpressure characteristics of metal accelerating explosive/high detonation heat explosive composite charge was verified by test, and compared with that of the metal accelerating explosive charge. The results show that the theoretical analysis and simulation calculation is consistent with experiment, detonation velocity and explosion heat of composite charge were between the limit parameters of composite charge explosive composition, the fragments and blast wave overpressure comprehensive energy optimal matching was got by adjusting the ratio of composite charge, the result can be applied to the optimization design of warhead.
