Active vibration suppression device and method for bridge vibration
The invention provides an active vibration suppression device and method for bridge vibration, belongs to the technical field of active control of bridge structures, and aims to solve the problem that a passive damper is generally adopted to improve the wind resistance of a bridge and cannot adapt to changing environmental conditions at present. Comprising a vibration monitoring module used for monitoring the vibration state of a bridge and a mass block installed on a box girder through an installation assembly. And the decision-making module obtains monitoring data of the vibration monitoring module, analyzes the data and controls the driving module to drive the mass block to move according to a set speed based on an analysis result, and the moving direction of the mass block is opposite to the vibration direction of the bridge. According to the invention, the mass block carries out corresponding active control motion along with the vortex-induced vibration response of the bridge, so that the effect of controlling the vortex-induced vibration of the bridge in multiple modes by using only one device is achieved.
本发明提出一种用于桥梁振动的主动抑振装置及方法，属于桥梁结构主动控制技术领域，以解决现有通常采用被动阻尼器来提高桥梁的抗风性能，不能适应变化的环境条件的问题。包括：用以监测桥梁的振动状态的振动监测模块，通过安装组件安装在箱梁上的质量块；驱动模块和决策模块，所述决策模块获取振动监测模块的监测数据，对数据进行分析，并基于分析结果控制驱动模块带动质量块按照设定速度移动，且所述质量块的移动方向与桥梁的振动方向相反。本发明中，质量块随桥梁的涡激振动响应进行相应的主动控制运动，达到仅用一种装置即可以控制桥梁多种模态下涡激振动的作用。
