Development and design of heavy truck engine parts require improved knowledge on solidification kinetics and development of material properties. A suitable tool to handle the complex shape and solidification kinetics is the computer simulation of the casting process.
The quality of calculated results is dependent on the thermo-physical properties used, boundary condition and the quality of kinetic models implemented for calculation of resulting metallographical structure and material properties. A good quality means a good correlation between simulated and measured properties.
The paper will present a casting simulation of a cylinder head in complex shape for a diesel engine cast in grey iron together with results from measured cooling curves and investigated material properties. The values of heat transfer coefficient were calculated for a simple shaped sample, cast in a shell sand mould and used then for simulation of the cylinder head. The calculated and measured cooling curves correlate well, as well as the calculated and measured hardness value do.
