General description of the research topic. The article presents a comprehensive study of traditional induction-dynamic mechanisms (with one disk and a fixed coil) and multi-core induction-dynamic mechanisms (linear pulse induction converters) with a movable coil and two disks. Actuality of the topic. Such induction-dynamic mechanisms are widely used in various fields, in particular, in electrical apparatus industry, where speed is one of the most important characteristics. The purpose of the article is a comparative analysis and refinement of the characteristics of the traditional induction-dynamic system with one disk and a fixed coil and multi-core one with a movable coil and two disks. Research method, scientific novelty. The calculations are based on the solution of the equations of the electromagnetic field and the equations for the electric circuit of the coil. Practical significance and main conclusions. During the calculations, the values of electromagnetic force and force impulse acting on the moving disk, energy losses in the system and electromagnetic energy of the system are determined. The results of the study are presented in the form of graphs, namely, the coil current and total magnetic energy for a traditional induction-dynamic mechanism with one disk and for multi-core one with two disks, Joule losses in a fixed coil and disk (in a traditional system) and in a moving coil and two disks (in a multi-core system), force impulse and electromagnetic force of a moving coil (in a multi-core system) and a moving disk (in a traditional and a multi-core system) total impulse of the moving parts of the induction-dynamic mechanism with a multi-core system, as well as the electromagnetic force and the total force acting on the moving parts of the induction-dynamic mechanism with a multi-core system. It is shown that the induction-dynamic mechanism with two disks is less effective in terms of electromagnetic force, impulse and electromagnetic energy than the induction-dynamic mechanism of the traditional layout.
