摘　　要：为研究装药壳体材料对爆炸威力的影响,对不同壳体装药在空气和混凝土靶中的爆炸破坏效应进行了数值模拟及试验研究。结果表明,在相同的装药情况下,碳纤维复合材料壳体装药爆炸产生的冲击波超压相对D 6A钢壳体装药的高。因碳纤维复合材料壳体装药爆炸时不产生破片,所以对远距离目标不造成破坏,而D 6A钢壳体装药爆炸时产生的破片对远距离目标具有一定的杀伤效应。从混凝土靶的爆炸破坏效应来看,碳纤维复合材料壳体装药在阻抗匹配方面要比D 6A钢壳体装药好,更利于爆炸冲击波的传播。在同样装药的情况下,碳纤维复合材料壳体装药爆炸对靶体爆炸驱动有效能量大于D 6A钢壳体装药。静爆试验证明了数值计算与试验结果相一致。In order to investigate the effect of explosive charge shell materials on blast effect, the blast effect of explosive charge with different shell materials in air and concrete target is researched by means of numerical simulation and experimental investigation. The results show that under the same explosive charge, the peak overpressure caused by the detonation of explosive charge with composite material shell is higher than that with D6A steel shell. Because of no fragment generated in the case of explosive charge with C-fiber shell, the distant target is not affected by the fragments effect. However, blast fragment effect is distinct in the case of explosive charge with D6A steel shell. According to the blast effect in the concrete target, the explosive with C-fiber shell is superior in the matched impedance as well as detonation propagation to the one with D6A steel shell. Under the condition of the same explosive charge, the effective energy produced by the detonation of explosive with C-fiber shell is bigger than that with D6A steel shell. Results of explosion test conform to the numerical simulation.
