Research on Structural Optimization of the Aluminum Alloy Wheel

The optimization design for a wheel was implemented in this paper. The rim stiffness finite element model, 13-degree impact strength finite element model and bending analysis finite element model of the wheel were established firstly. The influence of the rim stiffness, wheel impact strength and bending fatigue strength of the wheel were synthetically considered. The constrained variable metric method optimization procedure OPTIII based on the monitoring technology was applied on the optimization calculation. The results show that OPTIII has the characteristics of high convergence rate and the lightweight design of a wheel may be realized based on the optimization design method.
