| 摘 要： | 针对大跨度桥梁的颤振问题,研究了利用调谐转动惯量阻尼器(TRID)进行大跨度桥梁颤振的被动控制方法。建立了具有调谐转动惯量阻尼器的桥梁在均匀风场中的系统颤振运动方程,引入状态空间向量,求解颤振临界风速。以虎门大桥为对象,分析了TRID对提高临界风速的有效性及TRID参数对控制效果的影响。

| Abstract: | A passive vibration control method was proposed in this study to control flutter of longspan bridges by using tuned rotary inertia damper (TRID).The flutter motion equation was established to describe the behavior of long-span bridges (with TRID) under the action of uniform wind field.State space vector was used in the equation and the critical wind speed causing flutter was solved.This method was used in Humen Bridge and the efficiency of the TRID in increasing critical wind speed was analyzed.Also,the influence of parameters of TRID on vibration control effects was addressed. |

| Keywords: | tuned rotary inertia damper flutter of bridge critical wind speed |
