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2.232 MJ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.

Abstract:  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．
Key words: free-sliding in skew mine    aluminum foam    energy-absorption device    LS/DYNA
