摘要
黄山太平湖大桥的第１振型表现为桥塔的横向弯曲振动。经计算在脉动风荷载作用下，塔顶将产生较大的振幅。对该桥塔顶部设置的调质阻尼减振器（被动ＴＭＤ）的振动控制进行了研究，结果表明它对桥塔的振动有较好的抑制作用。
The frist oscillation mode of the Huangshan Taiping Lake Bridge(cablestayed bridge) is the transverse bending vibration.According to the analysis,the amplitude of oscillation of the tower top would be reasonably large under the fluctuating wind.The control of the vibration with the Passive Turned Mass Damper( Passive TMD) which was settled in the tower top was studied in this paper.The result indicated that the TMD can effectively restrain the vibration of the bridge.
