Research Rope Bridge Dynamic Characteristics And Vibration Control Method For Large-span Pedestrian Mountain

Pedestrian rope bridge as a suspension bridge, suspension bridge spanning both have alarge capacity, the advantages of beautiful appearance, but also has the construction of fast,economical, and easy to adapt to a variety of terrain conditions merit. Pedestrian ropebridge into full play the main cable and boom by large tensile strength characteristics underthe bridge tower height is not high you can still maintain a great leap ability, in our countryas well as numerous tourist attractions in central and western mountains have wideapplications difficulty in such areas or other bridge construction bridge construction is notonly large, but also easily lead to waste of resources in the area will result in disharmonywith the surrounding environment. Due to the use of the pedestrian suspension bridgepurposeful, compared with other types of bridges, is undoubtedly a relatively best choice.Firstly, the background and status of the pedestrian rope bridge will be described, todetermine the thesis research, then using ANSYS finite element software for large-spanpedestrian rope bridge were parametric modeling, using the control variable parameters foreach method are discussed, summed up the impact of structural parameters on the dynamiccharacteristics of the pedestrian suspension bridge, especially since the vibration frequencyto identify key parameters to optimize dynamic performance of the structure, followed by adiscussion in the pedestrian loads and wind loads pedestrian rope bridge vibration problemsand make control recommendations.Wind cable vibration control measures are widely used in practical engineering, throughpractical projects modal treatment, research in different forms of wind cable conditions,pedestrian rope bridge structure and the dynamic response of the displacement of thevibration frequency changes, summed up the wind cable lines for different rope bridgespan servant vibration control effect. Finally, different forms of wind cable pedestriansuspension bridge in the conditions of use for the future pedestrian suspension bridge isdesigned to provide experience.
