主要内容 | This research investigates the effectiveness of using multi-unit gyroscopic stabilizers (MUGS) to control flutter in long-span bridges. Flutter is a structural vibration caused by aeroelastic instability, which can lead to significant damage or even collapse of the bridge. The study involves developing a mathematical model of both the bridge and the gyroscopic stabilizers, simulating the dynamic response under various conditions, and performing sensitivity analysis. The focus is on how the placement, number, and control parameters of the stabilizers affect the bridge’s flutter response. The findings will provide theoretical support for bridge design and maintenance, optimizing the configuration of gyroscopic stabilizers to enhance the bridge's flutter resistance.
