Disc spring variable-stiffness friction damper
The invention discloses a disc spring variable-stiffness friction damper. The disc spring variable-stiffness friction damper comprises outer cover plates, a cambered surface friction plate, a steel base plate, a first high-strength bolt, a second high-strength bolt and a disc spring, wherein positioning round holes, first round holes and cambered surface grooves are formed in the outer cover plates; cambered surface protrusions are arranged on the two sides of the cambered surface friction plate, a strip-shaped hole is formed in the cambered surface friction plate, and the cambered surface protrusions are perpendicular to the strip-shaped hole; a second round hole is formed in the steel base plate; and the cambered surface friction plate and the steel base plate are clamped between the two outer cover plates, and the cambered surface protrusions are located in the cambered surface grooves. According to the disc spring 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 number of disc spring groups and the length of cambered surfaces, so that the energy consumption requirements under different conditions are met. According to the disc spring variable-stiffness friction damper, all the plates are simple and are connected through the high-strength bolts, only holes or grooves are formed in the plates, machining is convenient, assembly is easy, the assembly type requirement is met, and mass production is facilitated.
本发明公开了一种碟簧变刚度摩擦阻尼器，包括外盖板、弧面摩擦板、钢垫板、第一高强螺栓、第二高强螺栓以及碟簧；外盖板上开设有定位圆孔、第一圆孔以及弧面凹槽；弧面摩擦板的两侧设置有弧面凸起，且弧面摩擦板上开设有条形孔，弧面凸起垂直于条形孔；钢垫板上开设有第二圆孔；两块外盖板将弧面摩擦板和钢垫板夹在中间，弧面凸起位于弧面凹槽内。本发明可通过控制高强螺栓预紧力大小、碟簧组数量和弧面长度，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。本发明中所有版型较为简单，板内仅开孔或开槽，加工方便，通过高强螺栓连接，组装简单，满足装配式的要求，便于量产。
