Pendulum type tuned mass damper
The invention provides a swing type tuned mass damper which comprises a mass unit, a swing arm unit and an energy consumption unit, the mass unit comprises an upper mass block and a lower mass block, the upper mass block is in swing connection with a controlled structure through the swing arm unit, and the lower mass block is in swing connection with the controlled structure through the energy consumption unit. The lower mass block can be horizontally and movably supported on the controlled structure through a horizontal guide assembly; the energy dissipation unit comprises a linear damping assembly and a nonlinear damping assembly, the linear damping assembly is arranged at the bottom of the lower mass block, the nonlinear damping assembly comprises linear dampers symmetrically arranged on the two sides of the mass unit, and the upper mass block and the lower mass block are connected through the linear dampers. The vibration damper has the advantages that the occupied space is reduced under the condition of the same mass unit vibration frequency and effective mass, and the vibration damping effect is good.
本发明提供一种摆式调谐质量减振器，包括质量单元、摆臂单元和耗能单元，所述质量单元包括上质量块和下质量块，所述上质量块通过所述摆臂单元与被控结构摆动连接，所述下质量块通过水平导向组件可水平移动地支撑于所述被控结构；所述耗能单元包括线性阻尼组件和非线性阻尼组件，所述线性阻尼组件设于所述下质量块的底部，所述非线性阻尼组件包括对称设于所述质量单元两侧的直线型阻尼器，所述上质量块与所述下质量块通过所述直线型阻尼器连接。本发明具有在相同质量单元振动频率和有效质量的情况下减少占用空间，减振效果优良等优点。
