Active and passive integrated suspension type electromagnetically driven active tuning mass damper
The embodiment of the invention provides an active and passive integrated suspension type electromagnetically driven active tuning mass damper. The active and passive integrated suspension type electromagnetically driven active tuning mass damper comprises a suspension device, a mass block suspended below the suspension device, an electromagnetic driving device arranged below the mass block and aprotection base located below the electromagnetic driving device. A first arc-shaped structure is arranged at the bottom of the mass block, a second arc-shaped structure with the curvature consistentwith that of the first arc-shaped structure is arranged at the top of the electromagnetic driving device, a first electromagnetic induction element is installed on the mass block, a second electromagnetic induction element is installed on the electromagnetic driving device, different electromagnetic driving forces are formed by changing the current in the first electromagnetic induction element orthe second electromagnetic induction element, and the direction of the electromagnetic driving forces is parallel to the tangential direction of a track formed by the simple pendulum motion of the mass block. According to the active and passive integrated suspension type electromagnetically driven active tuning mass damper, an extra suspension component is avoided, the structure is simple and economical, a guide rod is not needed, and friction does not exist.
本发明实施例提供了一种主被动一体化悬吊式电磁驱动的主动调谐质量阻尼器，包括悬吊装置，悬吊于悬吊装置下的质量块，设置于质量块下方的电磁驱动装置，位于电磁驱动装置下的保护底座。所述质量块的底部设有第一弧形结构，所述电磁驱动装置的顶部设有与所述第一弧形结构的曲率相一致的第二弧形结构，所述质量块上安装有第一电磁感应元件，所述电磁驱动装置上安装有第二电磁感应元件，以通过改变所述第一电磁感应元件或第二电磁感应元件中的电流来形成不同的电磁驱动力，且所述电磁驱动力的方向与所述质量块作单摆运动所形成轨迹的切线方向相平行。本发明避免采取额外的悬浮构件，结构简单和经济，无需导向杆且不存在摩擦。
