Model of magnetic gun with respecting eddy currents

Leubner K., Doležel I., Laga R.

Poznan University of Technology Academic Journals. Electrical Engineering

2015

No. 81

21--29

A sophisticated mathematical model of the magnetic gun is presented and solved numerically. The model consists of three strongly non-linear and non-stationary differential equations describing the time-dependent distribution of magnetic field in the device, current in the field circuit and movement of the projectile. The numerical solution is carried out in the application Agros2D based on a fully adaptive higher-order finite element method. The results are processed in Wolfram Mathematica. The methodology is illustrated by an example and selected results are compared with experiment.
