| 摘 要： | 利用ABAQUS 6.14软件模拟了在不同壁厚下，材料为20钢双直径圆管吸能元件的液压胀形、折叠和自由翻转的过程.并分析了不同壁厚下液压胀形与折叠后的壁厚分布，准静态压缩翻转变形模式以及准静态压缩时翻转力与翻转半径与推导公式之间的关系.结果表明：壁厚减薄程度与管材初始壁厚大小有关；20钢双直径圆管成形后发生轴向压缩时其自由翻转的模式多为内管外翻；推导的翻转力与翻转半径理论公式与实际测得翻转力与翻转半径的结果比较吻合.

| Abstract: | Using ABAQUS 6.14 software to simulate the process of hydraulic forming and folding and free inversion of the original 20 steel double diameter tube with different thickness.The relationship between the thickness distribution of the hydraulic forming and folding,the mode of quasi-static compression deformation and the relationship between the inversion force and the inversion radius of the quasi-static compression and the formula are analyzed.The results show that the tube thickness reduction is related to the degree of initial tube thickness.The mode of self-reversal in the axial compression of 20-pipe double-diameter pipe is mostly inner tube valgus.The theoretical formula of the reversal force and the turning radius is consistent with the actual measured turning force and the turning radius. |
