Abstract

In practical application, bridge cranes are widely used to move materials. The main girder of bridge crane is prone to the deformation in high-temperature environments. In this paper, two working conditions of main girder are obtained by analyzing its deformation. The maximum deformation of main girder of 32t-22.5m single-girder bridge crane is calculated by Finite Element Analysis (FEA) in different working conditions. The maximum deformation and stress increase linearly with the hoisting loads. Moreover, the maximum deformation and stress increase nonlinearly with the working temperature by the thermal-mechanical coupling analysis and thermal-gravity coupling analysis. Therefore, the working temperature should be taken into consider to predict of the deformation of main girder. Finally, the results of thermal-mechanical coupling analysis provide a theoretical foundation for the deformation and lightweight design of the main girder of bridge crane.
