【 摘 要 】

Deformation force and forming quality are the important research focus in process of Magnesium (Mg) alloy wheel. In this paper, a process model of flow control forming (FCF) for the wheel was built, and its finite element model was given to simulate the FCF process at different extrusion speed (5 mm/s, 10 mm/s, 15 mm/s and 20 mm/s). The simulated results show that the FCF method for the wheel can reduce deformation force to less than 22000 kN, while there are cracks on rim of the wheel. The results are verified by the experiment and the cracks predicted by simulation are in good agreement with the experimental results.
