“…Due to the characteristics of high specific strength, good corrosion resistance, weldability [3] and especially secondary recycling [4], aluminum alloys have attracted a great deal of attention from researchers. Compared with other advanced materials such as ultra-high-strength steel, these alloys can achieve excellent weight reduction and better fuel economy [5]. Studies show that if aluminum alloy was used to replace steel, the mass of an automobile engine could be reduced by nearly 30%, the mass of a wheel could be reduced by nearly 50% and the total weight of an automobile could be reduced by 30~40% [6,7], showing a considerable benefit.…”

The squeeze casting process for an AlSi9Mg aluminum alloy flywheel housing component was numerically simulated using the ProCAST software, and orthogonal simulation tests were designed according to the L16 (4) 5 orthogonal test table to investigate the alloy melt flow rule under four factors and four levels each of the pouring temperature, mold temperature, pressure holding time and specific pressure, as well as the distributions of the temperature fields, stress fields and defects. The results showed that the flywheel housing castings in all 16 test groups were fully filled, and the thinner regions solidified more quickly than the thicker regions. Hot spots were predicted at the mounting ports and the convex platform, which could be relieved by adding a local loading device. Due to the different constraints on the cylinder surface and the lower end surface, the solidification was inconsistent, the equivalent stress at the corner junction was larger, and the castings with longer pressure holding time and lower mold temperature had larger average equivalent stress. Shrinkage cavities were mainly predicted at mounting ports, the cylindrical convex platform, the peripheral overflow groove and the corner junctions, and there was also a small defect region at the edge of the upper end face in some test groups.
