Open publisher page 4 citations

Abstract

According to the practical production of 200t bridge crane, the structure and operating conditions of the main girder were studied and the optimal mathematical model was established. Through determining the objective function and boundary constraint conditions, the finite element model was established based on ANSYS and the analysis results were obtained. Using the first order optimization method to optimize the calculating results and comparing with the initial sequence, it shows that the total volume of girder is decreased by about 19.4%. The structural optimization of the main girder gets a preferable economic benefit and provides a foundation for designing the bridge crane girder.
