Abstract：The mechanism analysis and reasons were carried out for the defects such as shrinkage and porosity in casting of
aluminum alloy wheels of commercial vehicles. Simulation analysis was carried out for the low-pressure casting process of
aluminum alloy wheels by using AnyCasting software. The possible defects in filling roll, filling oxide, particle tracking and
solidification sequence were simulated, and the causes of flange shrinkage were analyzed. According to the position,
distribution and cause of shrinkage defects of flange, the corresponding preventive measures were formulated and the
casting process was optimized. The results show that the common defects of aluminum alloy wheel hub can be eliminated
by using the optimized process, and the wheel quality is good.
