Self-resetting variable friction damper
The invention discloses a self-resetting variable friction damper which comprises a limiting main plate, a fixing plate, a high-strength bolt, a cylindrical spiral compression spring, a belleville spring, a friction plate, a welding plate and the like. The damper adopts modular assembly design and is simple to mount and design. The damper is formed by connecting a cylindrical spiral compression spring and an energy consumption friction unit in series, variable friction force is achieved by milling a steel plate, the friction force can be automatically adjusted according to the reaction of the structure, the pre-pressure of the cylindrical spiral compression spring is controlled to be larger than the maximum output force of the friction unit, and the self-resetting function is achieved. Meanwhile, the damper designed by the invention is small in size, and the design of other structures of the building is not influenced. The method is suitable for bridges and building structures, and the engineering practicability is high.
本发明公开了自复位变摩擦阻尼器，包括限位主板、固定板、高强螺栓、圆柱螺旋压缩弹簧、蝶形弹簧、摩擦片、焊接板等。阻尼器采用模块化装配设计，安装设计简单。该阻尼器由圆柱螺旋压缩弹簧和耗能摩擦单元串联而成，通过铣削钢板实现变摩擦力，摩擦力可以根据结构的反应，自动调节摩擦力的大小，并控制圆柱螺旋压缩弹簧的预压力大于摩擦单元的最大输出力，实现自复位功能。同时，本发明设计的阻尼器体积小，不影响建筑其余结构的设计。本专利适用于桥梁、建筑结构中，工程实用性强。
