Abstract：

To improve the material utilization and forming productivity, three-step hot forging process for automobile hub was simulated by AFDEX software applying the closed hot forging without flash process，and the effective strain distribution, metal flow, load-time curves and flow line etc., were obtained. By analyzing the simulated results, the die structure of hub forming was designed, and the formed hub was made by practical experiment. After checking the forming load, component size and metal flow line of the experimental hub, it is found that the requirements of the size with good forming and no significant defect is fully met，and is consistent with the simulation. So the numerical simulation based on AFDEX for hub forming is reliable and the forming process for hub is feasible.
