Finite Element Analysis on the Main Girder of Bridge Crane

This paper uses ANSYS software to establish finite element model for bridge crane girder. By the analysis and processing of solving, the maximum deformation and equivalent stress of the main girder and the natural frequency and vibration mode of the main girder of the top five order of the main girder. Determine whether the main girder meets the requirements of deflection, strength and stiffness by the analysis of calculation results. The calculated results have great help for the optimum design of main girder.
