Abstract

Shaping by means of reeling under the conditions of superplasticity using specialized reeling mills is a promising technology for manufacturing axisymmetric parts of gas turbine engines (disks and hollow shafts) based on heat-resistant alloys. Mathematical simulation is an efficient method for determining the energy and thermomechanical parameters of the technological process. This paper describes a methodology for constructing a finite element model for the reeling of parts under the conditions of superplasticity, as well as the results of simulation by the example of making a disk and a hollow shaft of heat-resistant alloys. The technique proposed can be used in developing a technology and equipment design for reeling axisymmetric parts (disks, hollow shafts) based on heat-resistant alloys under superplastic conditions.
