主　　题：Casting Mold filling Solidification Numerical simulation 

摘      要：The latest progress on the study of numerical simulation of mold filling and solidification process of shaped casting is reviewed. In mold filling process simulation of castings, the SOLA VOF algorithmis is improved in efficient free surface treatment and turbulence consideration, and parallel computational techniques are implemented to accelerate the fluid flow calculation time as well. Methods for predication of shrinkage defects of steel castings and S G. iron castings are developed based on the solidification simulation. In order to reduce the residual stress and deformation of castings, a combined FDM/FEM method is implemented for the modelling of stresses. Numerical models for the simulation of micro structure and prediction of mechanical properties of S G. iron are developed. The verifications and applications of the simulation software show that the models and techniques adopted in current research work are efficient and appropriate for the numerical simulation of shaped castings.
