Abstract

The paper studies the matters of numeric simulation of the processes of casting, crystallizing and cooling down to room temperature, and addresses the related problem of the stress-strain state of the casting process in manufacturing the cast parts of a gas turbine engine. The influence of the technological parameters of casting onto the development of the deformation defects was evaluated. The works were performed on incorporating predeformation into the burn-out model for compensating temperature deformations during casting, and on production and control of the above casting with predeformation.
