Abstract: The three-dimensional software Creo was used to establish a three-dimensional model of the wheel hub, and after importing into ANSYS Workbench, it was meshed to form a finite element calculation model and calculated, and the stress and deformation results under the limit working condition were obtained. According to the analysis and calculation results, the structural improvement plan is proposed and the verification calculation is carried out, which provides an important theoretical basis for the optimization design.
