镁合金汽车轮毂低压铸造数值模拟
Numerical Simulation of Low Pressure Die Casting of Magnesium Alloy Car Wheel
摘要
Abstract
In order to predict defects of a magnesium alloy wheel that may arise during the low pressure die casting, a three-dimensional mapping software was used to establish the solid model and the filling and solidification stages of the magnesium alloy wheel were simulated by the Procast software. Because the pouring velocity has a great influence on the state of filling, and the shrinkage can easily generate on the hot spot or isolated pool area, the research on pouring velocity, temperature, and flow field during the casting process of magnesium alloy wheels was conducted. The results show that the blowhole, shrinkage, dispersed shrinkage, and oxide inclusion at the top of the rim are eliminated effectively by reducing the pouring velocity. Adding chill on the part between the wheel rim and the wheel rib where the hot spot may exist can make this part solid firstly, so that the quality of the casting can be improved.关键词
