Abstract

The temperature field in the solidification process of sand mold casting electro-mobile aluminum alloy wheels was simulated.The mathematical model

geometrical model and FEM model of temperature field were established.The nonlinear features of materials and boundary conditions have been fully considered and the latent heat was treated by using equivalent specific heat method.The temperature fields in solidification process of sand gravity casting aluminum alloy wheels were simulated by FEM simulation Procast

and temperature field distribution was presented.The results show that the numerical simulation can describe well dynamic changes of three dimensional temperature field and provide a reference to improve aluminum alloy wheels quality

determination of solidification time and process optimitation.
