| Abstract: | Analyze the structure of the main girder of oversize gantry crane. Propose an optimization method of main girder structure based on genetic algorithm due to the equal intensity of design concept. Goal of the optimization based on the minimum weight to establish the mathematical model of girder structure optimization, then output the optimization results. Establishing finite element model of the main girder optimized, adding constraints and multiple working load to calculation the main girder deflection and stress value. Analyze the finite element analysis results and the optimize results to prove the validity of optimization theory. Provide important basis for the further optimization of the girder structure. |
