| Abstract: | This paper introduces the system composition of the deck crane of Ningbo Daxie No. 2 Bridge. In the design process of the deck crane, ANSYS finite element software is used to simulate and analyze the loading condition of the steel truss in the process of the deck crane. The analysis results show that the stress, deformation and stability of the steel truss of the bridge floor crane meet the requirements of the relevant specifications. The results show that ANSYS finite element analysis can simply and quickly calculate the stress state of the bridge deck crane, which is conducive to checking the stability and safety of the structure, and optimizing the structure design, which has important significance for guiding the practical project. |
