Variable-stiffness tuned mass inerter damping device for controlling vortex vibration and flutter of bridge
The invention discloses a variable stiffness tuned mass inerter damping device for controlling vortex vibration and flutter of a bridge, which comprises a support structure arranged on the upper surface of a bottom plate; the lever is rotatably arranged on the supporting structure; the second supporting piece is used for being arranged on the upper surface of the bottom plate in a sliding mode; the flywheels are rotatably arranged at the two end parts of the second supporting piece through cylindrical rotating shafts; the mass block is arranged on the lever in a sliding manner; the extension plate is fixedly connected with the mass block; a first connecting band; and a second connecting band. According to the variable-stiffness tuned mass inerter damping device for controlling vortex vibration and flutter of the bridge, the stroke of the mass block is reduced through the amplification effect of the inerter, the relative position of the mass block to the rotation center point of the lever is changed to achieve semi-active adjustment of the frequency of the TMDI, and the position of the supporting point of the lever relative to the center of the bridge is changed; therefore, vertical and torsional vibration of the bridge is controlled, and vortex vibration or flutter of the bridge is controlled.
本发明公开了一种控制桥梁涡振及颤振的变刚度调谐质量惯容阻尼装置，包括：支撑结构，用于设于底板的上表面；杠杆，可转动的设于支撑结构；第二支撑件，用于可滑动的设于底板的上表面；飞轮，通过圆柱转轴可转动的设于第二支撑件的两个端部；质量块，可滑动的设于杠杆；延伸板，与质量块固定连接；第一连接带；第二连接带。本申请提供的控制桥梁涡振及颤振的变刚度调谐质量惯容阻尼装置，利用惯容器的放大效应降低质量块的冲程，改变质量块对于杠杆转动中心点的相对位置实现半主动调节TMDI的频率，改变杠杆支撑点相对桥梁中心的位置，进而控制桥梁竖向和扭转振动，实现对桥梁涡振或颤振的控制。
