[FEM][Midas][Abaqus][Midas2Abaqus] 钢柱屈曲分析 (Buckling Analysis of Steel Column)

坚持实干、坚持一线、坚持积累、坚持思考,坚持创新。 底部固支的H型钢悬臂柱,顶部竖直向下作用轴压力,分析构件的屈曲模态。为了考虑翼缘或腹板的局部屈曲,可采用壳单元进行建模。本例分别采用Midas Gen及Abaqus软件进行模拟。 Midas Gen Model Midas Gen Results (a)一阶屈曲模态(屈曲因子:8.24E+005)(绕工字钢的弱轴) (b)二阶屈曲模态(屈曲因子:1.976E+006)(绕工字钢的强轴) (c)三阶屈曲模态(屈曲因子:1.976E+006)(绕工字钢轴向扭转) Midas2Abaqus Model 为了进行Abaqus分析,采用Midas2Abaqus软件进行模型转换。 Abaqus Model Abaqus Results (a)一阶屈曲模态(屈曲因子:8.26583E+005)(绕工字钢的弱轴) (b)二阶屈曲模态(屈曲因子:1.98061E+006)(绕工字钢的强轴) (c)三阶屈曲模态(屈曲因子:1.976E+006)(绕工字钢轴向扭转) 由以上两个软件分析结果可知,Midas Gen及Abaqus的分析结果基本一致,一阶屈曲模态为绕工字钢的弱轴,二阶屈曲模态为绕工字钢的强轴,三阶屈曲模态为绕工字钢轴向的扭转屈曲。 注释 ( Comments )   ( 如果您发现有错误,欢迎批评指正。邮箱:jidong_cui@163.com . 如果您喜欢这篇博文,请在上面给我 点个赞 吧!       …
