External damping device for stay cable
The invention provides a stay cable external damping device which comprises a shell, a preliminary displacement amplification assembly and a gear response amplification assembly are installed in the shell in a limiting mode, and one end of the preliminary displacement amplification assembly is connected with a stay cable through a top connecting rod; at the other end, the preliminarily amplified displacement is converted into rotation through the gear response amplification assembly, the rotation angular speed is amplified, and the gear response amplification assembly converts the amplified rotation angular speed into corresponding displacement through the linear displacement driving assembly and drives the external damper assembly to conduct acceleration energy consumption; the lower end of the external damper assembly is connected with a bridge deck through a bottom connecting rod. According to the device, the preliminary displacement amplification assembly can achieve a preliminary amplification effect on the infinitesimal displacement of vibration in a stay cable plane, the infinitesimal displacement is converted into rotation through the gear response amplification assembly, the rotation angular velocity is amplified, and then the infinitesimal displacement is converted into correspondingly amplified displacement through the linear displacement driving assembly; and therefore, the external damper assembly is driven to accelerate energy consumption.
本发明提供了一种斜拉索外置式减振装置，包括外壳，外壳内限位安装有初步位移放大组件以及齿轮响应放大组件，初步位移放大组件的一端通过顶部连接杆与斜拉索相连，另一端通过齿轮响应放大组件将初步放大的位移转换为转动并对转动角速度进行放大，齿轮响应放大组件通过直线位移驱动组件将放大后的转动角速度转化为相应位移并驱动外置阻尼器组件进行加速耗能，外置阻尼器组件下端通过底部连接杆连接桥面板。本发明通过初步位移放大组件能够对斜拉索面内振动的微小位移起到初步放大效果，微小位移通过齿轮响应放大组件转化为转动，并对转动角速度进行放大，再通过直线位移驱动组件转化为对应放大后的位移，从而驱动外置阻尼器组件进行加速耗能。
