Damping-adjustable friction pendulum support
The invention belongs to the technical field of structure vibration isolation, and discloses a damping-adjustable friction pendulum support. A down sliding face work mode is adopted, the damping-adjustable friction pendulum support comprises a sliding block and a sliding panel, a spherical friction pair is formed by the sliding block and the sliding panel, and a sliding face is arranged on the sliding panel. A coil is embedded in the sliding block. Symmetrically-arranged metal foam matrixes are mounted on the sliding panel, the top faces of the metal foam matrixes are lower than the top face of the sliding face, and therefore a damping clearance is formed between the metal foam matrixes and the sliding block. Magnetorheological fluid is soaked in the metal foam matrixes. When the magnetorheological fluid is not in the magnetic field area formed by the coil, the magnetorheological fluid is stored in metal foam. When the magnetorheological fluid is in the magnetic field area, the dampingclearance is filled with the magnetorheological fluid due to the action of magnetic field force. According to the damping-adjustable friction pendulum support, the semi-active control technology of rheological fluid is combined, and on the premise of preserving part of the original work mode of the friction pendulum support, the damping adjustable function is achieved; and meanwhile, by means ofthe characteristics of the metal foam, sealing of the magnetorheological fluid is guaranteed ingeniously.
本发明属于结构隔振技术领域，公开了一种阻尼可调式摩擦摆支座，采用下滑动面工作模式，包括构成球面摩擦副的滑块和滑动面板，滑动面板上设置有滑动面；滑块内部嵌装有线圈；滑动面板安装有对称设置的金属泡沫基体，金属泡沫基体的顶面低于滑动面的顶面，使金属泡沫基体与滑块之间形成阻尼间隙；金属泡沫基体的内部浸透有磁流变液。当未处于线圈形成的磁场区域内时，磁流变液储存在金属泡沫中；当磁流变液处于磁场区域内时，磁流变液由于磁场力的作用填充到阻尼间隙内。本发明结合流变液的半主动控制技术，在保留部分摩擦摆支座原有工作模式的前提下，实现其阻尼可调的功能；同时，利用金属泡沫的特性，巧妙的保证磁流变液的密封。
