ABSTRACT
The aim of the work is precise coupled electromagnetic-temperature field analysis using the finite element method of an induction heating system and creation of adequate field models at chosen control points. The obtained models have been applied in an optimization task, concerning special requirements for temperature distribution in the heated detail. The field analysis problem was solved as nonlinear, transient and axisymmetrical. The field models used in the optimization problem were based on the Response surface method and Design of experiment. The presented example refers to a real induction heating system. Heated details after plastic deformation and hardening are used for producing farm instruments.
