【摘要】 利用相似理论,对金属薄壁圆管轴向屈曲过程进行了相似性分析,并对金属薄壁圆管原型及其缩比后的模型进行了准静态试验,研究了金属薄壁圆管轴向压缩过程,对其吸能特性和相似律进行了分析。结果表明,在准静态轴向压缩下,原型和模型的屈曲变形基本相同,遵循相似律。更多还原

【Abstract】 The analogue theory is used to analyze the scaling law of axial buckling of metallic thin-walled circular tubes.The quasi-static axial tests are conducted on both the prototypes and the scaling models of thin-walled circular tubes.The process of thin-walled circular tubes subjected to axial compression has been studied.An analytical study is performed on the energy absorption characteristics and the analogue rule.The results show that the buckling behavior of the prototypes under quasi-static axial compression is basically consistent with the models,which accords with the analogue rule.更多还原
