摘要
针对装药壳体材料对爆破威力影响,对典型复合材料壳体、D6A钢壳体装药在空气中的爆炸破坏效应进行了数值分析及试验研究。研究表明,同样装药情况下,复合材料壳体装药爆炸产生的空气冲击波超压较钢壳体装药大;碳纤维复合壳体装药爆炸不会产生破片对远距离目标造成破坏;而D6A钢壳体装药爆炸产生的破片对远距离目标具有一定的杀伤效应。进行了2种材料壳体装药在空气中爆炸毁伤威力对比试验,试验超压测量结果与数值计算结果相一致。
The blast effect was researched by numerical simulation and experimental investigation. In the case of 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 no fragment was generated in the case of explosive charge with C-fibred shell, the distant target is not affected by the fragment effect. However, the reverse condition takes place in the case of explosive charge with D6A steel shell. Results of explosion test conform to the numerical simulation. According to the blast effect in air, the explosive with C-fibred shell is superior in the matched impedance as well as detonation propagation to the one with D6A steel shell. In the case of the same explosive charge, the effective energy produced by the detonation of explosive with C-fibred shell is bigger than the one with D6A steel shell.
