摘要
基于薄板的屈曲理论,通过有限元分析软件ANSYS对带有六边形孔的腹板进行了屈曲性能分析,求出了单孔及双孔腹板在纯弯作用下的屈曲形态和屈曲系数,并最终拟合了板的高厚比限值,可供有关设计参考。
Based on the buckling theory of thin plate,the paper analyzes buckling performance of web with hexagonal holes through finite element analysis software ANSYS,and obtains the buckling mode and buckling coefficient of web with single hole and double holes.Finally,the paper fits the depth-thickness ratio limits.These can be consulted by designs.
