Translation type passive tuned mass damper
The invention relates to the technical field of vibration control of building structures, in particular to a translational passive tuned mass damper which comprises a mass component, a spherical roller assembly and a first base which are sequentially arranged from top to bottom. The top of the first base and the bottom of the mass component are provided with opposite concave surface tracks respectively, and the spherical roller assembly is arranged between the opposite concave surface tracks in a rolling mode. The second bases are paired in the first direction and the second direction respectively and are fixed on the outer edge of the first base; the first base and the second base are connected through a detachable force transmission assembly so as to attenuate displacement of the mass component in the first direction and the second direction. By arranging the detachable spring assembly, the passive tuned mass damper can replace a spring according to the change of the natural vibration period of a building structure, so that the natural vibration period of the damper is changed, the bidirectional tuning function is achieved, and the damping effect is more stable.
本发明涉及建筑结构振动控制技术领域，尤其涉及一种平动式被动调谐质量阻尼器，包括从上至下依次设置的质量部件、球型滚轮组件和第一底座，第一底座固定于建筑结构水平面上，所述第一底座的顶部与所述质量部件的底部分别设有相对的凹面轨道，所述球型滚轮组件滚动设置在相对的凹面轨道之间；还包括分别沿第一方向和第二方向成对且固定于所述第一底座外缘的第二底座；所述第一底座与所述第二底座之间通过可拆卸的传力组件连接，以衰减所述质量部件沿所述第一方向和第二方向的位移。通过设置可拆卸的弹簧组件，使得被动调谐质量阻尼器可以根据建筑结构自振周期的变化而更替弹簧，以改变阻尼器的自振周期，实现双向调谐功能，减振效果更稳定。
