| 摘 要： | 为了控制桥梁结构风致振动,提出了间断型三向调谐质量阻尼器(TMD)的概念,旨在提高桥梁结构的颤振临界风速,并提出了间断型三向TMD控制系统及其相应的理论和计算方法.间断型三向TMD能同时控制桥梁结构横向、竖向和扭转三个方向的风致振动.通过最优控制理论计算得出系统的最优参数,通过风洞试验和Ansys软件模拟计算,得到重要结论:参数合理的间断型三向TMD系统能显著提高桥梁结构颤振临界风速. |

| 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. |
| Keywords: | discrete tuned mass damper three direction control wind resistance of bridge flutter Ansys software |
