铝镁合金轮毂低压铸造过程数值模拟

In this paper，three-dimensional entity modeling technology is applied for modeling the wheel, and mesh wheel to set the boundary conditions and experimental parameters. Comparative experiments were designed, and the numerical simulation was done to study the impact of mold temperature, melt temperature and time pressure curve on the filling time, order, stability and gas entrapment. The results showed that the mold temperature and melt temperature have little effect on the filling time, order, stability and gas entrapment, the main factor is the time pressure curve.
