为研究温压炸药和TNT炸药在圆筒装置内爆炸冲击波载荷的传播规律和分布特性,开展了圆筒装置内爆炸试验,分析了圆筒装置内冲击波的传播规律,对比了同质量两种炸药爆炸产生的冲击波超压和冲量的分布特性。结果表明:多波形叠加是圆筒装置内爆炸冲击波的特征,叠加效应随爆心距的增加而增强,温压炸药叠加效应更为显著;相比于同质量TNT,温压炸药爆炸冲击波冲量均值的增幅约为超压峰值均值增幅的2倍,在密闭空间更利于毁伤目标。

In order to investigate the propagation rules and distribution characteristics of the explosion shock wave loading on thermobaric explosive and TNT explosive inside cylindrical devices, the internal blast experiments were carried out in cylindrical device, propagation rules of shock wave were analyzed, distribution characteristics of overpressure and timing integral impulse of the shock wave about two explosives of same mass were compared. The results show that superposition is characteristic of the shock wave in cylindrical device, and the superposition effect increases gradually with the increase of the distance between explosion source and measuring point, and the superposition effect of thermobaric explosive is more obvious than TNT; The average value of timing integral impulse of the shock wave on thermobaric explosive increases by 20.3% compared with TNT, the increase is about twice the average value of overpressure peak, which is more conducive to damage target than TNT in closed space.
