Numerical Simulation of Squeeze Casting Based on SPH-FEM Coupling Method
The model establishment and simulation based on coupling analysis method of smoothed particle hydrody-namics(SPH)and finite element method(FEM)were described emphatically.The flow field and thermal stress field of squeeze casting process were numerically simulated,and the simulation program of SPH-FEM coupling analysis method was independently compiled.The simulation results of SPH filling process were compared with those of gen-eral commercial software,and the results are basically consistent.The simulation results of temperature field and stress field in the solidification process of FEM were analyzed.It is found that the cooling rate and effective stress value reach the highest at the thin wall of the side of the support part.The research shows that the developed numerical simulation program of squeeze casting process based on SPH-FEM coupling has accurate simulation results and reliable operation.
