基于阻尼耗能原理的高压输电塔风振抑制方法
Wind-induced vibration reduction technology of high-voltage transmission tower based on polymer damper
摘要
Abstract
Because the wind-induced vibration of transmission tower may reduce the fatigue strength of the transmission rod/tower, wire and hardware connections, and in severe cases can lead to tower or rod fall, the wind-induced vibration reduction was researched based on energy dissipation principle of damper. Firstly, the wind-induced vibration response of transmission tower-line system was analyzed with ANSYS software. Secondly, the vibration reduction strategy of transmission tower was put forward based on energy dissipation principle of damper. The effect of wind-induced vibration reduction with different damper layouts was designed and compared. At last, the program mentioned was implemented into transmission tower in Guangdong Province during the typhoon "Kai Tak" in August 2012. The results show that the wind-induced vibration energy can be dissipated effectively, as well as the amplitude of wind-induced vibration. During the typhoon "Kai Tak" in August 2012, the vibration acceleration of transmission tower is decreased by 60%-70% during 9-10 typhoon (speed at 21-24 m/s), which shows that it is an effective way to prevent strong winds disaster and improves the disaster prevention capacity.关键词
