间断型三向TMD桥梁颤振控制
Discrete Three-direction Tuned Mass Damperbased Control of Bridge Flutter
摘要
Abstract
To control the wind-induced vibration of the bridge structure, the paper presents a discrete three-direction tuned mass damper (TMD) control system to increase the flutter critical wind speed, and correspondingly, the theory and the calculation method. The horizontal, vertical vibration and torsional vibration can be well controlled with the system. Based on optimal control theory, the optimal parameters of the system are obtained. Wind tunnel test and the ansys simulation reveal that with the discrete three-direction TMD control system, the flutter critical wind speed of bridges improves significantly.关键词
