Abstract

In the article, methods of mathematical modelling are used to study interrelated electromagnetic, mechanical, and heat processes in a rail accelerator of conductive bodies. The multiphysical chain mathematical model of an accelerator has
been created. The way of improvement of traditional accelerator was proposed, which is the multistage construction that allows to increase substantially the electromechanical efficiency by reducing Joule losses in the rails. This is achieved by detachment from discharge circuit of those rails sections that are not involved in effective magnetic flux creation and perform the functions of current conductors only. In the example of small-caliber accelerator, the substantial efficiency rise and accelerator components heating reduction is demonstrated. References 7, tables 3, figures 9.
