Application of numerical simulation systems for the research of the blade casting process in blank production


The article focuses on the analysis of the results of computer simulation of the process of casting the turbine blade 24.400.538-1, including prediction of occurrence of casting defects. Engineering calculations have been carried out to model the stress-strain state of the casting during solidification and after the knockout of the casting from the mold. The internal structure of the casting was analyzed for the presence of microporosity. The analysis of the results of modeling the process of grain formation in the casting made it possible to predict the size and direction of grain growth in the casting during its crystallization. Thus, on the basis of in-depth research of the group technology of a complex representative of the most loaded turbine blade and the one most difficult to produce local places of occurrence of casting defects were identified and predicted taking into account the obtained results of simulating the casting process. This made it possible to reduce the amount of defects at the stage of actual production by 8% on the average.
