Abstract In order to investigate the impact characteristics of the reflection shock wave loading on the foam material, this paper deduced the reflection wave theory of shock wave. Some experiments to study the effect of parameters based on the shock tube experiment platform were done, including the density, the geometric parameters, and the sealed metal plate strength. The experimental results demonstrated that when the shock wave hit the foam material, as the specimen length raised as the velocity of the first reflected shock wave accelerated. Furthermore, the velocity of the reflection shock wave was increased with the specimen density went up. When a metal plate was enclosed at the top of the foam material, an obvious increment in the strength of the first reflected wave was observed, the strength of the reflected wave exhibited more stable, as the metal plate strength increasing. Moreover, the experimental results were consistent with the theoretical results. The research in this paper can provides some reference and guidance for using foam material to effectively mitigate the damage of shock wave.

反射冲击波对泡沫材料的影响

摘要 为了研究反射冲击波载荷对泡沫材料的冲击特性，推导了冲击波的反射波理论。基于激波管实验平台进行了一些实验来研究参数的影响，包括密度、几何参数和密封金属板强度。实验结果表明，当冲击波撞击泡沫材料时，随着第一次反射冲击波的速度加快，试样长度增加。此外，反射冲击波的速度随着试样密度的增加而增加。当泡沫材料顶部封闭金属板时，观察到第一次反射波的强度有明显的增加，反射波的强度表现得更稳定，随着金属板强度的增加。此外，实验结果与理论结果一致。本文的研究可为利用泡沫材料有效减轻冲击波的危害提供一定的参考和指导。
