摘要
文章推导了装有TMD的结构在考虑气动自激力以及抖振力作用下的动力微分方程;为了提高计算效率使用基于模态空间中虚拟激励分析手段,在对原始的桥梁结构进行耦合抖振分析后,对安装了TMD的桥梁-TMD系统进行耦合抖振分析,以抑制抖振响应;对某在建的跨江三塔悬索桥进行了原结构耦合抖振分析和TMD-结构耦合抖振分析,探讨了TMD控制参数对抑制大跨度桥梁抖振响应的影响。
The dynamic differential equations governing the motion of the structure with tuned mass damper（TMD） are established,in which the effects of aerodynamic self-excited force and buffeting force are taken into account.In order to enhance the computing efficiency,the pseudo-ecxited method in the mode space is used to analyze the coupled buffeting response to an original long-span bridge and a bridge-TMD system.A three-tower suspension bridge being built crossing the Yangtze River is taken as an example,and the buffeting analysis of the original bridge and the buffeting control analysis of bridge-TMD system are performed.The effect of TMD control parameters on restraining the response of coupled buffeting is discussed.
