为了控制河南艺术中心标志塔的风致振动,提出了一种采用十字形万向铰轴实现多向振动控制、采用摩擦阻尼片提供附加阻尼、采用放射型弹簧提供附加刚度的新型悬吊式TMD。根据标志塔结构的动力特性,设计加工了足尺TMD,通过实验室试验对其动力性能进行了测试,并将该TMD安装在实际结构上,依据实测频率和阻尼对其参数进行了现场调整。研究表明,该TMD装置具有构造简单,稳定性和持久性好等优点。 In order to control the wind-induced vibration of the sign tower of Henan Art Center, a new type of suspension TMD with multi-directional vibration control using a cross-shaped universal hinge axis, additional damping by using frictional damping plates and additional rigidity by using radial springs was proposed. According to the dynamic characteristics of the marker tower structure, a full scale TMD was designed and machined, and its dynamic performance was tested by laboratory tests. The TMD was installed on the actual structure, and its parameters were adjusted on site according to the measured frequency and damping. Research shows that the TMD device has the advantages of simple structure, good stability and durability.
