Three-dimensional interpretation of thermal field calculation scheme for equivalent plate during overlaying of wheelset axle journal

The authors studied a three-dimensional image of correspondence of the selected decomposition scheme of the specified solid cylinder into the equivalent plate. Temperature fields formed from the action of a moving point heat source on the surface of a given solid cylinder along a helical line of a given pitch and an equivalent plate are calculated depending on the depth of the layer under study.
Keywords: electromagnetic overlaying, temperature, equivalent plate, heat source
