Abstract
This paper mainly investigates the wind-induced vibration control of long span transmission line systems through wind tunnel experiment of aero-elastic model. This experiment is based on the engineering background of 500 kV long span transmission line system under construction in Jiangyin, China. Three kinds of vibration controls, in which suspended water-tank pendulum, viscoelastic damping pendulum and the combination of both are applied to the experiment The dynamic behavior is obtained through free vibration, and wind-induced response of long span transmission line system with or without the control device being tested at various wind speeds under fluctuating wind. The damping ratio and standard deviation of response are calculated and analyzed, and the results prove that these kinds of control are effective. The conclusion of this paper can be used for reference to practical design of wind-induced vibration control of long span transmission towers.
