This thesis is based on crane dynamic theory and finite element theory, and utilized software platform of ANSYS. It realizes model analysis and transient analysis of steel rope and bridge structure. The data and conclusion offered effective method to bridge crane design. The thesis mainly includes:According to crane dynamic theory, established relevant dynamic model, and analyzed the dynamic properties of the bridge structure of the bridge crane, including the natural frequency, the model shape and the dynamic stress. A way to analyse the dynamic response of the bridge structure of the bridge crane which takes into account the dynamic properties of the steel rope pulley block has been explored successfully.
