中文摘要：

半固体 A356 铝合金的一个明显的粘性模型被开发了，软件 Castsoft6.0 结合了模型被用来模仿汽车主人刹车柱体充满半固体 A356 铝合金泥浆的模子。模拟结果与实际充满过程一致，显示明显的粘性模型是可行的并且能被用来模仿半固体 A356 铝合金泥浆充满的模子并且能被用来优化充满的过程和设计死。一个更高的注射压力，一更高对汽车主人刹车柱体充满的模子在半固体泥浆，和更高的泥浆温度的门流动速度有益。

英文摘要：

An apparent viscosity model of semi-solid A356 aluminum alloy has been developed and the software Castsofl6.0 coupled with the model has been used to simulate the mould filling of an automobile master brake cylinder with the semi-solid A356 aluminum alloy slurry. The simulation results are in agreement with the practical filling process, indicating that the apparent viscosity model is feasible and can be used to simulate the mould filling of the semisolid A356 aluminum alloy slurry and can be used to optimize the filling process and the design of dies. A higher injection pressure, a higher ingate flow velocity of the semi-solid slurry, and a higher slurry temperature are advantageous to the mould filling of the automobile master brake cylinder.
