摘　　要：人行索道桥主梁刚度小、自重轻,行人过桥时易产生振动,影响桥梁正常使用。以某景区人行索道桥为研究对象,对其TMD阻尼器安装前和安装后2个工况进行人桥耦合振动分析研究,以验证结构振动特性和阻尼器安装效果。The girders of pedestrian cable suspended bridges exhibit small rigidity and dead weight, and vibration is easy to produce when pedestrians walk across bridges, so normal operation of bridges is affected. With a pedestrian cable suspended bridge in some scenic region as an object of study, this paper analyzes and studies pedestrian - bridge coupling vibration under 2 operating conditions before and after installation of TMD dampers to validate vibration properties of structures and installation effect of dampers.
