Lightweight Design of Shipbuilding Gantry Crane Structure Based on FEA

Abstract:

For the sake of working safely and stable, large-scale shipbuilding gantry crane was designed based on the principle of metal structure:3S,Strength,Stiffness,Stability. The detailed finite element analytical computation was successfully carried out on this structure, the stress and strain distribution of this structure were obtained under various actual operations. On the basis of it, the structural improvement was carried out, the result of design indicated that the stress was evident and the weight was lightened. This laid a foundation for the structure design of large-scale shipbuilding gantry crane.
