Frequency conversion lever tuned mass damper device and method
The invention discloses a frequency conversion lever tuned mass damper device and method. The frequency conversion lever tuned mass damper device comprises a base plate, a fixed support is vertically arranged at the top of the base plate, and the top of the fixed support is rotationally connected with a top profile frame; a spring telescopic mechanism and a damper body are arranged between the top profile frame on one side of the fixed support and the base plate, the top of the spring telescopic mechanism is connected with the top profile frame, the bottom of the spring telescopic mechanism is connected with the base plate, the top of the damper body is connected with the top profile frame, and the bottom of the damper body is connected with the base plate; a horizontal movement mechanism is arranged on the top profile frame, a mass block is arranged on the horizontal movement mechanism and used for driving the mass block to move front and back in the extending direction of the top profile frame, and the mass block is located on the side, away from the damper body, of the fixed support. And the spring telescoping mechanism and the horizontal movement mechanism are controlled and driven by the PLC movement control system. The damping device has the advantages of being adjustable in low frequency and remarkable in damping effect, vibration of a large structure can be effectively restrained within a wide frequency range, and the safety and comfort of the structure are improved.
本发明公开一种变频杠杆调谐质量阻尼器装置及方法，它包括基板，基板顶部立设有固定支座，固定支座顶部转动连接有顶部型材架；固定支座一侧的顶部型材架与基板之间设置有弹簧伸缩机构和阻尼器本体，弹簧伸缩机构顶部与顶部型材架相连，其底部与基板相连，阻尼器本体顶部与顶部型材架相连，其底部与基板相连；顶部型材架上设置有水平运动机构，水平运动机构上设置有质量块并用于驱动质量块沿顶部型材架延伸方向前后移动，质量块位于固定支座背离阻尼器本体的一侧；弹簧伸缩机构和水平运动机构均由PLC运动控制系统控制驱动。该发明具有低频可调、减震效果显著的优点，能够在宽泛的频率范围内有效抑制大型结构的振动，提高结构的安全性和舒适性。
