Damper vibration reduction system for restraining bridge vibration and implementation method
The invention discloses a damper vibration reduction system for restraining bridge vibration and an implementation method, and belongs to the technical field of structural vibration control. The system comprises a deformation displacement conversion amplification device and a damper, the two ends of the damper are connected with a bridge girder through the deformation displacement conversion amplification device, and when the bridge girder generates bending vibration, the deformation displacement conversion amplification device amplifies the corner displacement generated by the bending vibration and converts the corner displacement into horizontal displacement; a piston of the damper is driven to move by utilizing a horizontal displacement difference formed by conversion and amplification of the relative angle displacement, and the damper is reversely stretched to output damping force to act on the bridge girder so that vertical bending vibration of the bridge girder is inhibited. The invention aims to solve the problems that the damping force for restraining the vertical vibration of the main beam is not easy to apply and the restraining effect is unstable in the prior art, and the system is simple in structure, ingenious in design, easy to install and low in cost, and can increase the vertical damping of the bridge by arranging a plurality of groups of horizontally arranged damping devices on the main beam of the bridge, and thus the effect of better controlling the vertical vibration of the large-span bridge is achieved.
一种抑制桥梁振动的阻尼器减振系统及实现方法，属于结构振动控制技术领域。本发明包括形变位移转换放大装置和阻尼器，阻尼器两端均通过形变位移转换放大装置与桥梁主梁建立连接，当桥梁主梁发生弯曲振动时，形变位移转换放大装置将弯曲振动产生的转角位移放大并转换成水平位移，利用相对转角位移转换放大形成的水平位移差，带动阻尼器活塞运动，阻尼器反向拉伸输出阻尼力作用于桥梁主梁，从而抑制桥梁主梁的竖向弯曲振动。本发明研发目的是为了解决现有抑制主梁竖向振动的阻尼力不易施加、抑制效果不稳定的问题，本发明的构造简单、设计巧妙、易安装、成本较低，可以在桥梁主梁上通过设置多组水平放置的阻尼装置来增加桥梁竖向阻尼，以达到更好的控制大跨度桥梁竖向振动的效果。
