中文摘要：

针对结构抗爆炸冲击需求,提出了一种圆管吸能装置,并与横卧单、双圆管吸能装置进行比较。通过计算分析证明了该系统在冲击波作用下能够有效的吸收外来冲击能量,削弱冲击波荷载峰值,降低对下部结构的损伤破坏,提高结构抗力,是一种性能优良的抗冲击能量吸收装置。

英文摘要：

On a structure of anti-blast load aims to a new structure of tubes,a comparison has been carried out with lying single tube and double tube.This structure was proved by calculation that can absorb more blast energy and weaken the peak load by plastic deformation,so it is a superior energy absorbing structure of anti-blast load.
