【Abstract】 The finite element(FE) model of the road wheel was set up and validated by the test. Based on this model and analysis of optimization algorithm, the road wheel was designed effectively under the constraint of intensity and stiffness. The results showed that the weight of wheel disc, regarded as original scheme, had decreased over 10%,and the stress state had been improved evidently.更多还原
