| 摘 要： | 为研究输电线路中导地线对输电铁塔动力特性的影响,基于有限元软件ANSYS建立了输电塔及塔线体系有限元模型,采用仅考虑导地线质量作用、仅考虑导地线刚度作用、同时考虑导地线质量和刚度作用3种模型分别分析了输电塔动力特性,并与单塔模型进行了比较。结果表明,导地线的质量作用和刚度作用对输电铁塔动力特性均有影响,且质量作用影响较大,计算分析时不可忽略。

| Abstract: | In order to research the effect of transmission line on the dynamic characteristics of
power transmission towers, the finite element software ANSYS is applied to establish the model of
transmission tower and tower-line system. The dynamic characteristics of power transmission towers
are analyzed with three kinds of models, which include only considering the mass action of the
transmission lines, only considering the stiffness action of the transmission lines, and
considering both of the mass and stiffness action of the transmission lines. Compared with the
single transmission tower model, the results show that both the mass and stiffness action of
transmission line has impact on the dynamic characteristics of power transmission towers; meanwhile
the mass action has larger effect, which can not be ignored in analysis and calculation. |
