摘要
对６种规格的沿母线预制槽的低碳钢、不锈钢、铜圆柱管的２４个试件，在刚性锥头平台上（半锥角分别为 ４５°、 ２１．８°）进行了轴压下的试验；并对四种规格的低碳钢、不锈钢（每种规格材料由５个圆柱管组合）试件在半锥角为４５°刚性锥头平台上进行了组合试验，找出了各种试件的变形模态，并通过载荷－位移曲线分析了金属圆柱管能量吸收的全过程．
Experimental studies are carried out on 24 specimens of mild steel, stainless steel and copper metallic cylindrical tubes of six specifications under axial compress of rigid cone-shaped plate with cone semi-angles 21.8° and 45° and on 20 specimens of mild steel, stainless steel of four specifications of rigid cone-shaped plate with a cone semi-angle 45°. The distortion modes of all samples are obtained. The process of energy absorption is analyzed by load-displacement relation curves.
