摘要
介绍1种评估风载作用下耦合输电线路铁塔动态特性的方法。为此,建立了输电塔线体系在风载作用下动力响应的评估标准,并利用有限元模拟进行分析,结果表明,该能量评估标准能有效地检测结构动态特性。模拟结果表明,能量标准对大规模输电铁塔在强风载作用下的性能评估是非常有效的。
A method for estimation of dynamic characteristics of coupled transmission towers by the action of wind load is recommended.Therefore,estimation standard for dynamic response of power transmission towers by the action of wind load is established and analyzed by finite element models.The result shows that the energy estimation standard can examine dynamic characteristics of the structure effectively and the simulation result shows that the energy standard is effective in performance evaluation of large-scale transmission tower by the action of wind load.
