| Popis: | This study investigated on thermal deformation of AC4C aluminum alloy casting material for tire mold built in metal casting method. In this study, temperature, displacement and stress distributions of AC4C casting material occurred inside the mold were numerically calculated by finite element analysis (FEA). Also, temperature profiles of AC4C were experimentally measured to investigate the temperature characteristics during the solidification process in metal casting device. The result of this study revealed that the numerical result of temperature profiles predicted a rapid cooling from initial state to about 25 minutes, but the experimental result of it uniformly occurred from initial state to about 15 minutes by the phase change. However, the cooling patterns of two cases were almost similar results in the whole cooling process. Also, thermal deformation was generated by the difference of cooling temperature between the surface and inside of the casting from the results of displacement and stress distribution predicted by FEA. |
