External damping device for suspension cable of suspension bridge
The invention discloses an external damping device for a sling of a suspension bridge, and relates to the technical field of damping vibration attenuation devices. The dowel bar assembly comprises a lower dowel bar assembly, one end of the lower dowel bar assembly is used for being connected with the bottom of the sling, the other end of the lower dowel bar assembly is rotationally connected with the middle of the dowel lever, and the dowel lever is divided into a resisting arm and a power arm; one end of the upper dowel bar assembly is used for being connected with the sling, and the other end of the upper dowel bar assembly is rotationally connected with the end of the resisting arm; the damping structure is arranged at the end of the power arm and used for being fixed to the main beam. When the device is used, the characteristic that the displacement of the bottom of the sling is small and almost zero is utilized, the middle rotating point of the force transmission lever serves as a fulcrum and is divided into a resisting arm and a power arm, the other end of the upper force transmission rod assembly is rotationally connected with the end of the resisting arm, the damping structure is connected with the end of the power arm, and vibration is amplified and transmitted to the damping structure; the method has the characteristics of no need of arranging a special vertical support foundation and convenience in installation.
本发明公开了一种悬索桥吊索外置式阻尼装置，涉及阻尼减振装置技术领域，该装置包括传力杠杆，其用于与吊索间隔设置；传力杆组件，其包括：‑下传力杆组件，其一端用于与吊索的底部连接，另一端与传力杠杆的中部转动连接，将传力杠杆划分为阻力臂和动力臂；‑上传力杆组件，其一端用于与吊索连接，另一端与阻力臂的端部转动连接；阻尼结构，其设置在动力臂的端部，用于固定在主梁上。使用该装置时，利用吊索底部位移很小几乎为零的特点，将传力杠杆中部转动点作为支点，分为阻力臂和动力臂，上传力杆组件另一端与阻力臂的端部转动连接，阻尼结构与动力臂的端部连接，将振动放大传给阻尼结构，具有无需布置专门的竖向支撑基础，安装方便的特点。
