Self-resetting double-cavity graded friction damper
The invention relates to a self-resetting double-cavity graded friction damper which comprises a frame, a partition plate is arranged in the frame and divides the interior of the frame into a first cavity and a second cavity, a first friction plate is arranged in the first cavity, and a second friction plate and a third friction plate are arranged in the second cavity. The two ends of the third friction plate abut against the partition plate and the side wall, close to the second cavity, of the frame correspondingly, one end of the second friction plate penetrates through the partition plate and is in sliding connection with the first friction plate through two check blocks, a disc spring is arranged between the two check blocks, and a disc spring is arranged between the third friction plate and the frame. Graded friction energy consumption is conducted on large and small displacement of a building in a targeted mode, the self-resetting function is achieved all the time under the large and small displacement, complete resetting can be achieved more easily when the building is large in displacement and under the condition that energy consumption of a damper is large, and therefore residual deformation of the building does not exist.
本发明涉及一种可自复位的双腔室分级摩擦阻尼器，包括框架，框架内设置有隔板，所述隔板将框架内部分为第一腔室和第二腔室，第一腔室内设置有第一摩擦板，第二腔室内设置有第二摩擦板和第三摩擦板，第三摩擦板两端分别抵住隔板和框架靠近第二腔室的侧壁，第二摩擦板一端穿过隔板通过两个挡块与第一摩擦板滑动连接，两个挡块之间设置有碟簧，第三摩擦板与框架之间设有碟簧，本发明有针对性的对建筑物发生的大小位移进行分级摩擦耗能并在大小位移下始终发挥自复位功能，使得建筑物在大位移时，阻尼器耗能大的情况下也能更容易的实现完全复位，从而促使建筑物不存在残余变形。
