Abstrakt EN: Induction shrink fit in a gas turbine is modeled. The fit is realized by pressing of a heated steel wheel carrying the blades on shaft and its purpose is to transfer a relatively high torque in specific operation conditions. The paper deals with the numerical solution of the process that represents a nonlinear and nonstationary coupled problem characterized by interaction of magnetic field, temperature field and field of thermoelastic displacements. The methodology is illustrated by a typical example whose results are discussed.
