EXPERIMENTAL VERIFICATION BY THERMAL ANALYSIS OF THE '3D Sim' SOFTWARE FOR CASTINGS SOLIDIFICATION SIMULATION

摘要

The authors of this paper realized at "TRANSILVANIA" University of Brasov, a software for 3D solidification simulation for castings of eutectic alloys. The paper presents some results of the experimental researches done by the authors in order to verify this software. To verify the software there were compared the solidification time for a casting, experimentally determined by thermal analysis with the solidification time obtained by solidification simulation for the same casting. The study shows that the "3D_Sim" software leads to similar results as experimental ones. The solidification time obtained by simulation is a little bigger than that experimentally determined. This deviation can be explained by the errors induced by the thermocouples presence inside the mould in the experimental research as well as by the fact that the software doesn 't simulate flowing and cooling inside the gating system.
