摘要研究薄壁开孔圆管的轴向耐撞性有助于其在缓冲、吸能领域的广泛应用。通过分别考虑开孔区域和未开孔区域的能量吸收特征并引入材料的应变强化效应，根据塑性铰理论建立了轴向荷载下开孔圆管轴对称压溃模式的理论模型，得到了弯曲应变能、拉伸应变能、平均压溃力、比吸能的解析表达式。分析结果表明：该理论模型的预测结果与数值和实验结果相吻合；正则化平均压溃力会随半皱褶长细比的降低而显著增加；单层孔数对正则化平均压溃力的影响会随管壁厚度的增加或孔半径的减小而降低；比吸能可通过减少单层孔数或减小孔半径提高。

Abstract：The investigation of axial crashworthiness of thin-walled holed circular tubes is helpful for their wide application in buffering and energy absorption fields.By considering the energy absorption behaviors of holed and unholed regions respectively and introducing the strain-hardening effect of material, a theoretical model for the axisymmetric mode of a holed circular tube under axial crushing was proposed based on the plastic hinge method.The expressions for bending strain energy, stretching strain energy, mean crushing force and specific energy absorption were deduced.The results show that the theoretical predictions agree well with the experimental and simulation results; the normalized mean crushing force increases obviously with the decrease of the half-fold slenderness ratio; the effect of the hole number in each row on the normalized mean crushing force decreases with the increase of the wall thickness of tube or the decrease of hole radius.The specific energy absorption increases with the decrease of the hole number in each row or the reduction of hole radius.

Key words： thin-walled structure holed circular tube axial crashworthiness crushing force specific energy absorption
