Numerical Simulation of Filling and Solidification Process of Cast Aluminum Alloy Wheels and Its Defects Prediction
Through the numerical simulation on liquid metal filling and solidification process of cast aluminum alloy wheels,using Anycasting software,the time and temperature distribution of filling and solidification process and its microstructure were predicted.The position and reasons of filling and solidification defects,such as gas volume,shrinkage cavity and shrinkage,were predicted through coupling calculation for flow field and temperature field.The improvement process was proposed.So the production cycle shortens and the quality of cast aluminum alloy wheels improves.
