Variable-stiffness friction damper
The invention discloses a variable-stiffness friction damper. The variable-stiffness friction damper comprises outer cover plates, cambered surface friction plates, a rubber plate, a first steel base plate, a second steel base plate, a first high-strength bolt, a second high-strength bolt and a third high-strength bolt, wherein the two outer cover plates are located on the outermost layer, the two cambered surface friction plates are located on the secondary outer layer, the rubber plate is located in the middle, the first steel base plate and the second steel base plate are located at the two ends of the rubber plate respectively, and a certain distance is formed between the second steel base plate and the rubber plate; and cambered surface groove arcs are formed on the outer cover plates, cambered surface protrusions arranged arranged on one side face of the cambered surface friction plates, and the cambered surface protrusions are located in cambered surface grooves. According to the variable-stiffness friction damper, the friction force and the length of working displacement can be controlled by controlling the pretightening force of the high-strength bolts, the thickness of the rubber plate and the length of cambered surfaces, so that the energy consumption requirements under different conditions are met, and the structural stiffness is improved through the change of the friction force. According to the variable-stiffness friction damper, all the plates are simple and are connected through the high-strength bolts, the assembly type requirement is met, assembly is easy, and mass production is facilitated.
本发明公开了一种变刚度摩擦阻尼器，包括外盖板、弧面摩擦板、橡胶板、第一钢垫板、第二钢垫板、第一高强螺栓、第二高强螺栓和第三高强螺栓；两块外盖板位于最外层，两块弧面摩擦板位于次外层，橡胶板位于中间，第一钢垫板和第二钢垫板分别位于橡胶板的两端，第二钢垫板与橡胶板之间具有一定间距；外盖板上开设有弧面凹槽弧，弧面摩擦板的一侧面上设置有弧面凸起，弧面凸起位于所述弧面凹槽内。本发明可通过控制高强螺栓预紧力大小、橡胶板厚度和弧面长度，来控制摩擦力的大小和工作位移的长度，以适应不同情况的耗能需求，并且通过摩擦力的变化提高结构刚度。本发明中所有板型较为简单，通过高强螺栓连接，满足装配式要求，组装简单，便于量产。
