研究了低密度填充材料（例如铝蜂窝或泡沫）在准静态加载条件下对方箱柱的轴向抗压强度的影响。数值模拟表明，就获得最大能量吸收而言，用铝蜂窝填充箱形柱比加厚柱壁更有利。通过在柱中填充中等或高强度的泡沫铝也可以获得优异的比能量吸收。开发了平均破碎力与填料强度之间关系的简单公式。此外，与未粘合的填充相比，粘合剂的存在显着增加了能量吸收。
The effect of low density filler material, such as aluminum honeycomb or foam, on the axial crushing resistance of a square box column under quasi-static loading conditions is studied. Numerical simulation shows that in terms of achieving maximum energy absorption, filling the box column with aluminum honeycomb can be preferable to thickening the column wall. Superior specific energy absorption is also obtained by filling the column with moderate or high strength aluminum foam. Simple formulas for the relationship between mean crushing force and the strength of filler are developed. Moreover, the presence of adhesive increases energy absorption significantly compared to unbonded filling.
