摘要:Wind-induced vibration control of power transmission tower using pounding tuned mass damper is studied in the paper. The power transmission tower, which is often a high and flexible structure, is very susceptible to wind-induced vibrations. To reduce the wind-induced vibration of a transmission tower, a new type of vibration control device that pounding tuned mass damper (PTMD) is proposed in the PTMD, a limiting collar with viscoelastic material laced on the inner rim is installed to restrict the stroke of the tuned mass and to dissipate energy through collision. The pounding force is modeled based on the Hertz contact law. A 55 m tower is selected to verify the effectiveness of the PTMD. The wind field is generated based on Kaimal spectrum using harmonic superposition method. The power transmission towers without control and with the PTMD are analyzed, respectively. Results show that the PTMD is very effective in reducing the wind-induced vibration and the vibration control performance improves as the external wind load increases.
