Multivariate calculations of the electrodynamic linear accelerator with permanent magnet support

Andrzej Waindok, Bronisław Tomczuk, Paweł Piekielny
The multivariate calculations of the electrodynamic accelerator with permanent magnet support and a ferromagnetic core were presented in the paper. The calculations were made with using the Magnetostatic module of a Maxwell/ANSYS software. The purpose of these calculations was to determine the size and location of the permanent magnets in terms of maximizing the force acting on the projectile. In the presented paper three cases have been analyzed. In order to perform a comparative analysis of the obtained results of calculations, the dimensions of the rails, projectile and outer dimensions of the core were keep constant.
Keywords: electrodynamic accelerator, multivariate calculations, force calculation, finite element method modelling
