| Abstract: | According to the structure characteristics of girder,a finite element model of the bridge is established based on ANSYS software.Finite element model analysis was conducted to the girder of box bridge crane,and the preceding six order natural frequency of the girder and the corresponding vibration model were concluded.The dangerous area of the main girder vibration was found out,which could provide a theoretical basis for bridge crane girder structure design and transformation. |
