NUMERICAL SIMULATION FOR RADIAL FATIGUE TEST OF AN ALUMINUM ALLOY WHEEL

Open publisher page 4 citations

Abstract

By translating the dynamic contact to a transition cushion which nodes are movable to some extent,a method to deal with the problem occurred in the contact between tyre and rim is proposed. The cushion is meshed using pentahedron elements which nodes are shared with tyre and rim,and the contact forces are transferred. The stiffness and thickness of this cushion is so small that can be ignored to the stiffness of the wheel. Considering the tangent force of the rolling contact between driving wheel and test wheel is relative small,an equivalent radial force is used to replace the load from driving wheel. The finite element model of the wheel is established and the results shown in the final fatigue simulation demonstrates that the model is validated by comparing with the conclusions of experiments and preceding research.
