Computer simulation of induction hardening of moving flat charge

The computer simulation of the process of induction surface hardening based on the example of cutter knife hardening is presented. For the two-dimensional (2-D) arrangement, the total system containing inductor, moving charge, cooling system, and energy source as a series bridge transistor inverter has been simulated. The source parameters (voltage and frequency) depend on the load parameters obtained by numerical calculations of the coupled fields. For the 3-D model, the influence of the inductor-charge arrangement on the temperature distribution near the charge edge has been estimated.
