Self-adaptive friction energy consuming and vibration reducing device for bridge beam structure
The invention discloses a self-adaptive friction energy consuming and vibration reducing device for a bridge beam structure. The self-adaptive friction energy consuming and vibration reducing device comprises a base, a displacement conversion rack, a displacement amplifying assembly and a friction energy consuming assembly. The displacement conversion rack is fixedly installed on the end portion of a bridge beam. The displacement conversion rack moves horizontally along with horizontal vibration of the bridge beam. The displacement amplifying assembly and the friction energy consuming assemblyare fixedly installed on the base. One end of the displacement amplifying assembly is in transmission connection with the displacement conversion rack, and thus the horizontal vibration of the bridgebeam is converted into rotating motion of the displacement amplifying assembly. The other end of the displacement amplifying assembly is in transmission connection with the friction energy consumingassembly, and thus while displacement of the horizontal vibration of the bridge beam is amplified indirectly, the rotating motion of the displacement amplifying assembly is conveyed to the friction energy consuming assembly. By means of friction energy consuming, braking of the rotating motion of the friction energy consuming assembly can be achieved, effective braking is obtained under heat energy consumption and dissipation generated by friction, and energy consuming and vibration reducing of the bridge beam are good.
本发明公开了一种桥梁结构自适应摩擦耗能减振装置，其包括底座、位移转换齿条、位移放大组件和摩擦耗能组件，位移转换齿条固定安装于桥面梁的端部，位移转换齿条跟随桥梁的水平振动而平移，位移放大组件和摩擦耗能组件均固定安装于底座，位移放大组件的一端与位移转换齿条传动连接，以将桥梁的水平振动转化为位移放大组件的旋转运动，位移放大组件的另一端与摩擦耗能组件传动连接，以间接放大桥梁的水平振动的位移的同时，将位移放大组件的旋转运动传送至摩擦耗能组件，摩擦耗能组件则通过摩擦耗能以实现摩擦耗能组件的旋转运动的制动，在摩擦产生的热能耗散下得到有效的制动，桥梁的耗能减振良好。
