Movable flow suppression device for bridge vortex vibration and control method of movable flow suppression device
The invention discloses a movable flow suppression device for bridge vortex vibration and a control method of the movable flow suppression device. The movable flow suppression device comprises a plurality of movable flow suppression units, and each movable flow suppression unit comprises a control module, a first wind speed sensor, a second wind speed sensor, a first movable flow suppression assembly and a second movable flow suppression assembly; the first movable flow restraining assembly and the second movable flow restraining assembly comprise flow restraining plate assemblies, first damper assemblies and second damper assemblies. The first damper assembly and the second damper assembly are connected with the two ends of the flow restraining plate. The control module controls the driving module corresponding to the movable flow suppression assembly to work according to wind speed data collected by the first wind speed sensor or the second wind speed sensor, the rotating angle of the movable grid plate is adjusted, and then the ventilation rate of the flow suppression plate is adjusted. The method has the effects of changing the aerodynamic configuration of the bridge and improving the mechanical damping of the bridge, not only optimizes the bridge structure from the vortex vibration source, but also has a good vibration reduction effect after the structure starts vibration.
本发明公开了一种用于桥梁涡振的活动抑流装置及其控制方法，所述装置包括多个活动抑流单元，活动抑流单元包括控制模块、第一风速传感器、第二风速传感器、第一活动抑流组件和第二活动抑流组件；第一活动抑流组件和第二活动抑流组件包括抑流板组件、第一阻尼器组件和第二阻尼器组件；第一阻尼器组件和第二阻尼器组件与抑流板的两端连接；控制模块根据第一风速传感器或第二风速传感器采集的风速数据控制对应活动抑流组件的驱动模块工作，调整活动栅格板的转动角度，进而调整抑流板的透风率。本发明兼具改变桥梁气动外形与提高桥梁机械阻尼的作用，不仅从涡振源头上对桥梁结构进行优化，且在结构起振后也起到良好的减振效果。
