Rolling type passive tuned mass damper
The invention relates to the technical field of building structure vibration control, in particular to a rolling type passive tuned mass damper which comprises a mass ball, a first base, a second base, a force transmission assembly and a connecting device. The mass ball body is arranged in a ball concave surface track at the top of the first base in a rolling manner; the connecting device is of a frame structure and is horizontally connected to the middle of the mass ball in a sleeving mode so as to move in the horizontal direction when the mass ball rolls. The second bases are fixedly arranged on the outer edge of the first base in pairs in the first direction and the second direction respectively, and the first direction is perpendicular to the second direction. The top of each second base is provided with a force transmission assembly, and the force transmission assemblies are connected with the connecting devices so as to attenuate the displacement of the connecting devices in the first direction and the second direction. The force transmission assembly comprises a spring and a damping piece.
本发明涉及建筑结构振动控制技术领域，尤其涉及一种滚动式被动调谐质量阻尼器，包括：质量球体、第一底座、第二底座、传力组件和连接装置；所述质量球体滚动设置于所述第一底座顶部的球凹面轨道内；所述连接装置呈框架结构，水平套接在所述质量球体的中部，以在所述质量球体滚动时发生水平方向位移；所述第二底座分别沿第一方向和第二方向、成对且固定设置于所述第一底座的外缘，所述第一方向垂直于所述第二方向；每一所述第二底座的顶部设置传力组件，所述传力组件与所述连接装置连接，以衰减所述连接装置沿所述第一方向和第二方向的位移；所述传力组件包括弹簧和阻尼件。
