摘要
调谐质量阻尼器(简称TMD)是最早的一种结构振动控制装置,对于控制结构的风振反应具有非常明显的效果。文章主要介绍其中的一种TMD装置-单摆式TMD,并尝试将单摆式TMD应用于风力发电塔。利用单摆式TMD的减振消能作用,减小风力发电塔因风力作用产生的振动,从而减小振动引起的发电机故障和风力发电塔损坏。
The Tuned Mass Damper （TMD） is one of the oldest structural vibration control devices, and it has a very clear effect on controlling structural wind-induced vibrations. This paper introduced a TMD de- vice-Pendulum-Type TMD, and tried to use Pendulum-Type TMD for wind power towers. The pendulum- type TMD is uesd for damping energy dissipation and reducing the vibration generated by wind power towers due to wind loading, thereby reducing the wind turbines＇ failure and wind power towers＇ damage caused by vibration.
