Primary Study On Interior Ballistics Of A Small-caliber Electromagnetical Rail Gun

The technique of rail gun system is an important part of the electrical magneticlaunch technique. This dissertation is written for the problems which we usually met intheory and practice of the process of the pre-research in the domain of rail gun system.The major components of the dissertation are organized as the following.1. Discuss the basic work principle and the theory research of armatures. By the modelof the armature efficiency, we compute the efficiency of three armatures and analyzethe each other characteristics.2. In order to find the disciplinarian of rail gun characteristic and the relations betweenthe variational loads and the PNF network, a model of simple rail gun and capacitorbank is so built. Under the background of lumped parameter, we solve the PFNnetwork equation by Crout decomposition method and quantificationally simulatethe model by Runge-Kutta method.3. On the basis of the upper model, we optimization design an actual applied rail gunby penalty function method and calculate the reasonable design parameters. Weanalyze the produced elements of the parameters.4. We build a model ofβmagnetic probe in magnetic field measure. On the basis ofthe model, we calculate and analyze the variational law of induction electromotiveforce of magnetic probe. For the use of lab, we make an application process inmessure.
