Abstract
A wheel hub is a key rotor component of automobile. Nowadays alloy wheel hubs are used more and more widely. They are typically lighter for the same strength and provide better heat conduction. As we know that do a FEA (finite element analysis) is necessary before and after the alloy wheel hubs have been made. In this paper, a detail analysis was done with FEM (finite element method), and the stress distribution of wheel hub we got was consistent with the real distribution. Also the FEA results show that the maximum stress is much less the yield stress and the working safety factor is less than the allowed safety factor and it is useful for further work such as fatigue life prediction and reliability assessment.
