Abstract

In this paper we describe a numerical model and a construction of an electromagnetic launcher (EML) consisting of ten copper coils located serially. The solenoids were mounted on the pipe-shaped slideway, inside which, the ferromagnetic core was moved driven by the coils magnetic force. The paper presents the model of an EML based on circuit approach involving lumped parameters which were obtained by means of a finite element methods (FEM). The numerical representation contained a mechanical part with introduced friction coefficients. In the article we proposed an algorithm which enabled us to fit the numerical model to the constructed device by selection of these friction parameters values. Thus, we were able to compare the signals from computer simulations and measurements which were taken during laboratory tests.
