Bidirectional passive tuned mass damper and tuning method
The invention relates to the technical field of vibration control of building structures, in particular to a bidirectional passive tuned mass damper and a tuning method. The bidirectional passive tuned mass damper comprises a chassis, a mass sphere, a support, a restraining device, a connecting device and a force transmission assembly; the mass ball body is arranged on the chassis in a rolling manner; the restraining device is of a hemispherical frame structure and horizontally sleeves the upper portion of the mass sphere. The supports are oppositely arranged on the outer edge of the base plate in the first direction and the second direction respectively, and the first direction is perpendicular to the second direction. Each support is provided with a force transmission assembly, the connecting device is of a telescopic structure, and the connecting device is connected with the restraining device and the force transmission assemblies so as to attenuate displacement generated when the mass ball vibrates along with the building structure. The single mass ball is placed on the base plate with the groove to replace an existing swing type TMD device for lifting a single ball, the vertical building space is saved, and the space utilization rate is increased. And meanwhile, the'detuning 'of a traditional rolling type TMD device can be remarkably improved, and the bidirectional vibration reduction effect is achieved.
本发明涉及建筑结构振动控制技术领域，尤其涉及一种双向被动调谐质量阻尼器以及调谐方法，包括：底盘、质量球体、支座、约束装置、连接装置和传力组件；质量球体可滚动放置于底盘上；约束装置为半球形框架结构，水平套设于质量球体上部；支座分别沿第一方向和第二方向相对设置于底盘的外缘，第一方向垂直于第二方向；每一支座上设置传力组件，连接装置为可伸缩结构，连接装置连接约束装置与传力组件，以衰减质量球体随建筑结构振动时产生的位移。通过将单个质量球体放置于具有凹槽的底盘上，代替现有的将单个球体吊起的摆式TMD装置，节约竖向建筑空间，提高空间利用率。同时，能够显著改善传统滚动式TMD装置的“失谐”，实现双向减振效果。
