摘要
依据一维击波绝热透、反射理论和冲击波在空气、水中的衰减规律,分析了水中空气隔层对水下爆炸冲击波衰减的原理,并通过两次小药量模型实验对分析结果进行了验证.结果表明,空气隔层不仅可以削弱水中冲击波峰值压力,而且可以有效减少冲击波的冲量和总能量,从而可以有效防止水中爆炸冲击波对保护目标的破坏.
The principle of the air interlayer to weaken the shock wave is analyzed, based on the theory of one-dimensional shock wave insulation transmission and reflection, the attenuation rule of shock wave in air and underwater medium. The theoretical result was verified by two experiments of minimum explosive model. And the result indicates that the air interlayer not only could weaken the peak pressure, but also effectively absorbs the impulse and the total energy of shock wave, thus effectively reducing the damage to the protected object incurred by underwater shock wave.
