MODELING OF ELECTROMAGNETIC PROCESSES IN ELECTROTECHNICAL COMPLEXES FOR REDUCING RESIDUAL STRESSES

It was developed the axisymmetric mathematical model for calculating the instantaneous current density in the electrode system, which is part of the electrical complex to reduce the residual stresses. It was determined the instantaneous electromagnetic force affects the non-ferromagnetic conductive disc and consequently the pressure force of the electrode on the non-ferromagnetic conductive plate and the current spreading in the electrode contact area with a non-ferromagnetic conductive plate, calculated density distribution of the magnetic forces and the contact pressure zone. The resulting electromagnetic field is the superposition of electromagnetic fields was found.The distribution of current density and electromagnetic forces which is a prerequisite to the explanation of the phenomenon changes of residual stresses in the contact area of the electrode with a non-ferromagnetic conductive plate was analyzed.
