Influence of transmission line on wind-induced response of tower-line system
摘要
Abstract
[Purposes]The paper aims to study the influence of the coupling between transmission line and tower on the wind-induced dynamic response of the tower-line system.[Methods]Combined with the example of a tower-line system(three towers and two lines),numerical calculation and wind tunnel tests of an aeroelastic model were conducted.A finite element model of the above tower-line system was established with ABAQUS software,and the wind load generated by the harmonic synthesis method was used as input along the downwind direction.The Newmark-β method was used to solve the dynamic response of the system in the downwind direction.The wind-induced vibration coefficient of the system was calculated and compared with various codes.[Findings]The numerical analysis results are in good agreement with the experimental results,and the wind-induced vibration coefficients are all higher than the recommended values in the code.[Conclusions]The existence of transmission lines improves the aerodynamic damping of the structure,resulting in the acceleration response of the tower-line system being lower than that of a single tower.The wind-induced vibration coefficient increases with height,with a local mutation on account of the local mass increase of the cross arm.In practice,when calculating the wind-induced vibration coefficient of the transmission tower structure,the influence of transmission lines on the cross arm should not be ignored,and the suggested values of various codes should be considered comprehensively.关键词
