Abstract
Reducing the deformation of the transport bracket was the basic means to improve the mate precision between the large tonnage round bar and the bracket. The finite element model of the bracket was established and the actual loading conditions of the bracket for transporting the large tonnage round bar were analyzed by ABAQUS. The deformation and the weak areas of the bracket were investigated by the finite element analysis. The optimization model was obtained by the methods of replacing the type of the channel steel, improving the bracket structure and arranging fulcrums. These methods were adopted selectively to optimize the bracket structure based on the bracket’s maximum deformation demand. The finite element analysis not only shortened the design cycle, reduced the design cost, but also provided technical support for the bracket structure design.
