摘要:

区域冲突和恐怖袭击等爆炸环境造成的人员伤亡事件频频发生,且爆炸引起的人体损伤也已成为现代战争中士兵的主要致伤形式。针对人体抗爆炸冲击波防护的迫切需求,设计制作模拟人体的硅胶试验段,利用激波管试验研究一种柔性充液管结构的冲击波衰减作用,探索将冲击波的能量转化为管内的液体内能和动能,实现冲击波能量的有效转移和耗散。研究结果表明,通过协调冲击波作用下的液体流动耗能和液体自身吸能(凝胶化),最高可以衰减35%的超压峰值和30%的比冲量。相关研究对于提高人员爆炸冲击防护水平具有重要的研究意义和应用前景。

Abstract:

In recent years, the casualties caused by regional conflicts, terrorist attacks, and other explosive environments occurred frequently, causing widespread concern at home and abroad. Body injury caused by the explosion has become the main form of injury to soldiers in modern war. Here the attenuation effect of the liquid-filled tube structure for human body protection on the shock wave is mainly studied through shock tube test. Through the liquid-filled tube, the kinetic energy of shock wave is converted into the internal energy and kinetic energy of liquid in the tube, and the transfer and dissipation of the shock wave energy are realized with the release of liquid and its energy absorption. The results show that the protective structure can attenuate the peak overpressure by up to 35% and the specific impulse by 30%. The results could provide an important reference for human protection against blast shock waves.

Key words: liquid-filled structure, shock wave protection, shock tube, overpressure, impulse
