Multi-stage frequency conversion eddy current composite damping friction pendulum support
The invention discloses a multi-stage variable-frequency eddy current composite damping friction pendulum support, and belongs to the technical field of shock insulation (vibration) and vibration reduction (vibration reduction) of engineering structures, the multi-stage variable-frequency eddy current composite damping friction pendulum support comprises a support top plate and a support bottom plate, the support top plate is mounted above the support bottom plate, and multi-stage variable-frequency sliding surfaces are symmetrically arranged on the lower surface of the support top plate and the upper surface of the support bottom plate; the center position of the multi-stage frequency conversion sliding face is a plane, the curvature radius of the multi-stage frequency conversion sliding face is gradually reduced from the center to the outside, conductor plates are arranged on the multi-stage frequency conversion sliding face of the support top plate and the multi-stage frequency conversion sliding face of the support bottom plate, a cavity is formed between the support top plate and the support bottom plate, and a damping block, an electro-permanent magnet and an electro-permanent magnet bottom plate are arranged in the cavity. The damping block is slidably connected into the cavity, and the electro-permanent magnet is fixed to the periphery of the damping block through the electro-permanent magnet bottom plate. Composite damping energy consumption is achieved through eddy current damping and friction damping, and seismic mitigation and isolation control under the action of extreme disasters such as earthquakes and typhoons is achieved through the multi-stage frequency conversion sliding face.
本发明公开了一种多级变频电涡流复合阻尼摩擦摆支座，属于工程结构隔震(振)、减(振)技术领域，包括支座顶板和支座底板，支座顶板安装在支座底板的上方，支座顶板的下表面与支座底板的上表面均对称设置有多级变频滑动面，多级变频滑动面中心位置处为平面，多级变频滑动面的曲率半径由中心向外逐级递减，支座顶板与支座底板的多级变频滑动面上均设置有导体板，支座顶板与支座底板之间设有空腔，空腔内设置有阻尼块、电永磁铁及电永磁铁底板，阻尼块滑动连接于空腔内，电永磁铁通过电永磁铁底板固定于阻尼块的周向。本发明利用电涡流阻尼及摩擦阻尼实现复合阻尼耗能，并通过多级变频滑动面实现了地震、台风等极端灾害作用下的减隔震控制。
