The purpose of the project is to improve the technical systems and devices of scientific, industrial and defense purposes at the expense of pulsed electromechanical converters and electrophysical technologies. This will increase efficiency, improve parameters, reduce the magnetic fields of scattering and improve the quality control of devices. Research methods are mathematical modeling based on solving equations of electromagnetic, mechanical and thermal fields using finite element method, simulation methods, computer calculations, experimental research in laboratory conditions. The obtained recurrence relations for calculating the interrelated electromagnetic, mechanical and thermal parameters of a linear pulse electromechanical converter (LPEС). The best indicators are in the LPEС with the inductor circuit, which forms an aperiodic current excitation pulse with the connection of an additional capacitive accumulator. LPEС is most effective with a coil anchor, and the LPEС with a ferromagnetic anchor is the least effective. The induction-type LPEС screen is advisable to be made of real steel, and the screen and the electromagnetic-type LPEС anchor should be made of ideal steel. The combined magnetic-electromagnetic screen makes it possible to increase the efficiency of the converter. Substantiated concepts of a high-speed inductive current limiter with an additional superconducting screen, an electromagnet-induction type LPEС and a ballistic laser gravimeter with an induction-dynamic catapult. A physico-mathematical model of the electromagnetic-acoustic transformation process has been developed. The general solution of the differential equation of forced torsional oscillations in an infinite rod is fulfilled. Developed information-measuring electromechanical transducers for assessing the surface quality of ferromagnetic metal products. The research of electrophysical processes in perspective linear electromechanical accelerators is carried out.
