摘要
通过ANSYS有限元结构分析软件建立架空输电线路钢管塔模型,分别对6种不同钢管壁厚和内径的工况进行五阶屈曲模态分析。结果表明,钢管内径越大,钢管壁越厚,钢管塔整体稳定性越好;一阶和三阶屈曲模态下的钢管塔稳定性较差,二阶、四阶和五阶屈曲模态下的钢管稳定性相对较好。
Through the steel tube tower model of overhead transmission line is established by ANSYS finite element structural analysis software,the fifth-order buckling modes of six steel tubes with different wall thickness and inner diameter are analyzed.The buckling analysis of six different steel pipe wall thickness and inner diameter working conditions are carried out under the fifth order mode.The results show that the larger the inside diameter of the steel pipe and the thicker the wall thickness,the better the overall stability of the steel pipe tower is.The stability of steel tube tower under the first and third order buckling modes is poor.Order buckling modes of the second,fourth and fifth have relativelygood stability.
