Multi-stage friction damper and damping method
The invention relates to the technical field of shock absorption, in particular to a multi-stage friction damper and a shock absorption method. The multi-stage friction damper comprises a main cylinder, an auxiliary cylinder and a damping assembly. The main cylinder is connected with the auxiliary cylinder, a first cavity is formed in the main cylinder, a second cavity is formed in the auxiliary cylinder, and the cross section of the inner wall of the main cylinder changes in the axial direction; the damping assembly comprises a piston and a sliding block, a first damping hole is formed in the piston, a second damping hole is formed in the sliding block, a groove is formed in the circumferential wall of the piston, the sliding block is installed in the groove, pre-pressing springs are arranged on the sliding block and the bottom of the groove, and the pre-pressing springs can push the sliding block to move away from the piston. And the second damping hole is exposed out of the groove. According to the invention, under different earthquake inputs, the building safety can be further improved by matching different damper forces, the multi-level response control of the structure is realized, and the structure is simple and reliable.
本发明涉及减震技术领域，尤其涉及一种多级摩擦阻尼器及减震方法。多级摩擦阻尼器，包括：主缸、副缸和减震组件；所述主缸和副缸连接，所述主缸内具有第一腔室，所述副缸内具有第二腔室，所述主缸的内壁横截面沿着轴向变化；所述减震组件包括活塞和滑块，所述活塞上设置有第一阻尼孔，所述滑块上设置有第二阻尼孔，所述活塞周壁上设置有凹槽，所述滑块安装在所述凹槽内，且滑块和凹槽槽底设置有预压弹簧，所述预压弹簧能够推动滑块远离活塞移动，并使第二阻尼孔露出所述凹槽。通过本发明，当不同地震输入下，匹配不同阻尼器出力可以进一步提升建筑安全，实现结构多级响应控制，而且结构简单、可靠。
