Control beam spring damping device and control method

The invention provides a bridge spring damping device and a control method. A spring damper is configured to control the bending moment of a bridge, reduce the vibration amplitude of the bridge, and reduce the bridge damage caused by the vibration. The spring damping device is composed of a simply supported beam system and a spring bending moment control system. The simply supported beam system consists of a beam, a fixed hinge support and a rolling support. The spring bending moment control system consists of a fixed end, a time lag controller, a spring controller and a control beam. The bridge spring damping device uses the spring damper to control the bending moment of the bridge, and the controller occupies a small space and is easy to install. 本发明专利提出种桥梁弹簧减振装置与控制方法，利用弹簧减振器对桥梁进行弯矩控制，减小桥梁的振动幅值，减小振动导致的桥梁损伤。弹簧减振装置由简支梁系统、弹簧弯矩控制系统两个部分组成。简支梁系统由梁、固定铰链支座和滚动支座组成。弹簧弯矩控制系统由固定端、时滞控制器、弹簧控制器和控制梁组成。桥梁外伸弹簧减振装置，利用弹簧减振器对桥梁进行弯矩控制，控制器占用空间小，易于安装。
