The low-frequency tuned mass damper comprises a gear transmission system, a mass unit and a spring damping system, the gear transmission system comprises a driving wheel and a driven wheel which are connected in a meshed mode, the driving wheel is connected with a first transmission rod, and the driven wheel is connected with a second transmission rod; the mass unit comprises a mass block with adjustable mass and a first connecting rope, one end of the first connecting rope is wound on the first transmission rod, the other end of the first connecting rope is connected to the mass block, the mass block is hung in the air, and the spring damping system comprises an extension spring, a damper, a second connecting rope and a frame. The extension spring is provided with a connecting end and a fixed end which are oppositely arranged, one end of the second connecting rope is wound on the second transmission rod, the other end of the second connecting rope is connected to the connecting end of the extension spring, and the fixed end of the extension spring is connected to the steel box girder through the frame. And meanwhile, the control requirement of multi-order vertical bending mode vortex-induced vibration can be met.
本发明公开了一种低频调谐质量阻尼器，包括齿轮传动系统、质量单元和弹簧阻尼系统，齿轮传动系统包括啮合连接的主动轮和从动轮，主动轮上连接有第一传动杆，从动轮上连接有第二传动杆，质量单元包括质量可调的质量块和第一连接绳，第一连接绳的一端缠绕于第一传动杆上，另一端连接于质量块，质量块悬挂于空中，弹簧阻尼系统包括拉伸弹簧、阻尼器、第二连接绳和框架，拉伸弹簧和阻尼器同向设置，拉伸弹簧具有相对设置的连接端和固定端，第二连接绳的一端缠绕于第二传动杆上，另一端连接于拉伸弹簧的连接端，拉伸弹簧的固定端通过框架连接于钢箱梁，本发明的低频调谐质量阻尼器不仅占用空间小，同时能够适用于多阶竖弯模态涡激振动的控制需求。
