Optimization of simulation parameters in the process of spraying a metal die
Vlček, Ondřej ; Šotka, Pavel (referee) ; Krutiš, Vladimír (advisor)
This thesis, prepared for Škoda Auto, deals with the optimization of die casting simulation parameters in software ProCast. The aim was to develop and validate a methodology for inputting die spray parameters. The optimization itself was performed on a high pressure die casting simulation for an engine block casting. The temperature field was taken from the real die using a thermographic camera and then compared with the simulation. The parameters of the simulation were adjusted according to the experimentally obtained data and literature, and the course of optimization required changing not only the parameters related to the external treatment, but also the material models, or changing the heat transfer coefficient between the die and the casting. By the procedure, the temperature field of the original simulation, which differed from reality by more than 100 °C, was optimised so that the results at the measured locations did not reach a difference of more than ± 20 °C. Therefore, the procedure used can be applied as the required methodology for optimising further simulations.
