Object of research – electromechanical processes and indicators of linear pulse electromechanical converters of multicore configurations. Subject of research – linear pulse electromechanical converters of multicore configurations of power and speed purpose. Research methods. Mathematical modeling of electromagnetic, mechanical and thermophysical processes in linear pulse electromechanical converters of pulse action was used to solve the tasks to analyze the electromechanical characteristics and establish the influence of the shape of the excitation current on the efficiency of the converters. Experimental studies of linear pulse electromechanical transducers of multicore configuration were performed on experimental stands, which allowed to test device models. The following scientific results are obtained in the work: – the classification of linear pulse electromechanical converters of multicore configurations, which include ferromagnetic, coil and continuous conductive armature, was further developed; – the mathematical model of the linear pulse electromechanical converter due to inclusion of the ferromagnetic, coil and continuous electrically conductive anchors which interact with a mobile anchor is improved. The mathematical model, which is implemented in the COMSOL Multiphysics software environment, contains interconnected electrical, magnetic, mechanical and thermal processes and takes into account magnetic and thermophysical nonlinear dependencies; – for the first time the peculiarities of the course of electromagnetic processes are established and the electrical, magnetic and power indicators of linear pulse electromechanical converters of multi-core configurations of power purpose are determined. It is shown that almost all converters of multi-arc configurations provide an increase in the amplitude and magnitude of the pulse of electrodynamics forces in comparison with the converter, which has one continuous conductive armature; – for the first time the influence of geometrical parameters of movable and fixed electrically conductive armatures that interact with the movable inductor was established, which allowed to increase the speed indicators of the linear pulse electromechanical converter; – for the first time it is established that when excited by oscillatingattenuating, aperiodic and aperiodic with feeding forms of current in converters of multicore configurations the magnitude of the electrodynamics force pulse increases in comparison with the converter having one continuous electrically conductive armature.

Повний текст джерелаThesis for a Doctor's degree in Engineering Sciences by specialty 05.09.01 – Electrical Machines and Apparatus. – National Technical University “Kharkov Polytechnic Institute”, Kharkov, 2003. The dissertation deals with designing electromechanical impulse induction converters (EIIC) with liquid-nitrogen-cooled cryoresistive windings. On the basis of generalization of accumulated data in impulse electromechanics, a technique for designing cryogenic EIICs has been developed which takes into account interrelated electrical, magnetic, thermal, and mechanical complex processes with nonlinear critical parameters. The basic mechanisms of power and energy EIIC functioning which result in linear motion of the armature when the converter is excited from a capacitive accumulator or a constant-voltage source have been revealed. Structure-geometry, circuit, and design approaches for perfecting single- and multi-stage EIICs with valid parameters have been suggested. Experimental data have been obtained to validate developed mathematical models and engineering solutions. The main research results have been utilized and implemented at execution of seven state and commercial research projects, in research enterprises, and for students’ training.
