摘要
文章以截面形状系数、板件高厚比为主要参数,研究了冷成型不锈钢矩形管轴心受压构件弹性屈曲时板组相关性能。首先利用有限元软件Abaqus对直角矩形管轴心受压构件进行弹性屈曲分析,得到截面板件的弹性屈曲系数的建议公式。然后通过对计算数据进行分析来讨论截面形状系数和板件高厚比与弹性系数的关系。
The paper studies the relative properties of the plate group when the cold formed stainless steel rectangular tube axial compression members are subjected to elastic buckling,taking the section shape coefficient and the ratio of the thickness to height of the plate as the main parameters.Firstly,the elastic buckling analysis of rectangular rectangular tube members under axial compression is carried out by using Abaqus,and the suggested formula of elastic buckling coefficient of cross-section plate is obtained.Then,the relationship between the shape coefficient of the section,the ratio of height to thickness of the plate and the elastic coefficient is discussed by analyzing the calculation data.
