中文摘要：
研究泡沫铝“三明治”结构应用于大冲击能量吸能装置的设计，给出了泡沫铝材料用于吸能装置的设计方法与步骤，设计出可吸收2．232MJ能量的新型斜井跑车防护装置．利用LS／DYNA进行该装置的碰撞仿真分析，发现泡沫铝在高速冲击中逐层压溃，具有很好的缓冲吸能效果；在冲击过程中，瞬时吸能速率随着泡沫铝变形的加剧和结构强度的提高而增大，冲击中泡沫铝“三明治”结构出现粘结失效．
英文摘要：
Sandwich structure with aluminum foam core was applied in large-shock-energy absorption device and its design method and steps were presented. A new protecting device of free-sliding in skew mine which could absorb 2. 232 MJ energy was developed. Crashing simulation analysis on this device by LS/DYNA found that aluminum foam was steamed roller layer by layer and had good performance in absorbing energy. During the shock process, instant energy-absorption velocity would increase with the aggravation of aluminum foam core deformation and the enhancement of structure strength, and the conglutination of sandwich structure was broken.
