Bow string type inerter negative stiffness damper for vibration control of high-rise structure
The invention discloses a bowstring type inerter negative stiffness damper for vibration control of a high-rise structure. The bowstring type inerter negative stiffness damper comprises a prestressed cable and a damping structure. One end of the prestressed cable is connected with the top of the high-rise structure, and the other end is connected with the ground; one end of the damping structure is connected with the prestressed cable, and the other end is connected with the high-rise structure; the damping structure comprises a shell, a driving end, a hydraulic cylinder, a piston rod and an energy consumption assembly. The hydraulic cylinder is fixed in the shell; one end of the driving end is connected with the prestressed cable, the other end of the driving end penetrates into the shell and extends into the hydraulic cylinder to be connected with the piston rod, and the other end of the piston rod penetrates out of the hydraulic cylinder to be connected with the energy dissipation assembly in the shell. The damper not only can be installed on a high-rise structure, but also can enhance the damping effect.
本发明公开了一种用于高耸结构振动控制的弓弦型惯容负刚度阻尼器，包括：预应力索和阻尼结构；预应力索的一端与高耸结构的顶部连接，另一端与地面连接；阻尼结构的一端与预应力索连接，另一端与高耸结构相连接；阻尼结构包括：外壳、驱动端、液压缸、活塞杆以及耗能组件；液压缸固定于外壳内部；驱动端的一端与预应力索连接，另一端穿设入外壳内，并延伸至液压缸的内部与活塞杆连接，活塞杆的另一端穿出液压缸后与外壳内部的耗能组件连接。本发明中阻尼器不仅可以安装在高耸结构上，还可以增强减震效果。
