Barbashova M. Improvement of methods testing the electromagnetic characteristics of thin-walled sheet metals in electromagnetic forming

Object of research: the processes interaction of pulsed electromagnetic fields with thin-walled metal with different electromagnetic characteristics. Goal of research: improvement of methods testing of electromagnetic characteristics thin sheet metal for use in magnetic-pulsed treatment. Methods of research: analytical methods for solving tasks in electrodynamics, numerical methods of linear algebra, methods of differential and integral calculus, the method of comparison of experimental research on the stand installation using samples of different thickness with known parameters. Theoretical and practical results: methods of testing electrical conductivity and permeability of thin sheet metal in a magnetic impulse attraction specified portions of the sample processing in operating frequency of existing fields are developed. Scientific novelty is in improvement methods of testing electromagnetic characteristics of thin-sheet metal, in power magnetic pulsed effects, taking into account the amplitude values and frequency characteristics of excited fields, and their dependence on electrical parameters. The Implementation: the practical value of the thesis is confirmed by the implementation of regulations on the basis of the Industrial Group "U.P.E.C." (Kharkov) and STO PP "Svistun G.D." (Kharkov). The results of dissertation research are used in the educational process KhNADU (discipline "Advanced technologies in AV", the course "Physics" to "Electromagnetism and its application in the practice of modern vehicle repair"). Application field: the engineering and in repair and maintenance of vehicles.
