Friction damper
The invention provides a friction damper. The friction damper comprises a cylinder body and a force guiding device, wherein a cavity is formed in the cylinder body, the force guiding device is arranged in the cylinder body, damping force exists between the part, located in the cavity, of the force guiding device and the cylinder body, the part, extending out of the cylinder body, of the force guiding device and the cylinder body are connected with other assemblies respectively, and when the force guiding device moves under impact force, the larger the movement displacement is, the larger the damping force between the force guiding device and the cylinder body is. According to the friction damper, damping force is increased along with increase of displacement, so that certain rigidity and energy dissipation capacity necessary for shock absorption are provided for a structure, and the energy dissipation capacity is enhanced along with increase of the displacement of the structure; and the displacement response of a building structure can be effectively controlled during a large earthquake, the horizontal rigidity and damping of the structure are both increased, and the stability and safety of the structure can be greatly enhanced.
本发明提出了一种摩擦阻尼器，包括缸体，所述缸体内设置有空腔；以及设置在所述缸体上的导力装置，所述导力装置位于所述空腔的部分与所述缸体之间存在阻尼力，伸出缸体外的部分与缸体分别连接其他组件；其中，所述导力装置在受到冲击力而移动时，移动的位移越大与所述缸体之间的阻尼力越大。本发明的阻尼力随着位移的增大而增大，为结构提供一定的刚度和减震必要的耗能能力，且耗能能力随着结构的位移增大而增强；大震时可有效的控制建筑结构的位移响应，结构的水平刚度与阻尼均增大，可极大的增强结构的稳定性与安全性。
