Multi-dimensional tuned mass damper

The invention discloses a multi-dimensional tuned mass damper. The mass damper comprises an external sleeve, an internal sleeve, a center mass block unit, a vertical spring unit, a vertical damper unit, a horizontal spring unit and a horizontal damper unit. The center mass block unit is connected with the internal sleeve through the horizontal spring unit, the horizontal damper unit and a roller. The internal sleeve is connected with the external sleeve through the vertical spring unit, the vertical damper unit and the roller. The external sleeve is fixedly connected with an engineering structure. The multi-dimensional tuned mass damper can achieve multi-dimensional vibration control over the structure, and is applicable to the vibration control over the engineering structure under actions of dynamic loads such as strong wind, vehicles and earthquakes. 本发明公开了种多维调谐质量阻尼器，包括外部套筒、内部套筒、中心质量块单元、竖向弹簧单元、竖向阻尼器单元、水平向弹簧单元、水平向阻尼器单元；所述中心质量块单元通过水平向弹簧单元、水平向阻尼器单元及滚轮与内部套筒连接，所述内部套筒通过竖向弹簧单元、竖向阻尼器单元及滚轮与外部套筒连接，所述外部套筒与工程结构固定连接。本发明
