摘要
利用MTS810型材料试验机对Q215钢蜂窝夹芯结构进行了准静态压缩试验，分析了其结构参数对抗压强度和比吸能值的影响。结果表明：Q215钢蜂窝夹芯结构具有良好的吸能特性，比吸能值达到5～38kJ·kg^-1；沿x，y方向压缩时，抗压强度和比吸能值均随面板厚度与夹芯厚度比的增加而增大；沿z方向压缩时，抗压强度和比吸能值均随胞壁厚度与胞壁边长比的增加而增大。
The quasi-static compressive experiments of plain carbon steel Q215 were conducted on MTS810 tester. The effect of structure parameters on specific energy-absorption and compressive strength was analyzed for steel honeycomb structures. The results show that honeycomb structures of plain carbon steel Q215 were characterized by excellent energy-absorption capacity with the specific energy-absorption of 5-38 kJ · kg^-1. The compressive strength increased with the ratio of face thickness to core thickness for x and y direction compression. Meanwhile they increased with the ratio of cell wall thickness to cell length for z direction.
