Analytical model of gun firing mechanism dynamics

This bachelor thesis is devoted to creation of the analytical model of the dynamics of gun firing mechanism, that is used for design of individual parts of the mechanism, allowing the primer to be initiated properly. This analytical model has been verified by experimental measurement of the real mechanism operation from Brno Combo shotgun using a high speed camera Vision Research Phantom v710. In addition, the minimal energy, needed for initiation of FOCCHI 616 (.209 TYPE) primer, was experimentally measured using the test device and the high-speed camera. The results of experimental measurement of minimal initiation energies were compared with the experimental data from Sellier & Bellot primer producer
