Abstract

The study of barrel vibration is important for the performance of firing Weapons .In this paper the finite element method is used for modelling the barrel and determining its characteristics .A complete analysis of the course of affecting forces on barrel during the whole period of action is carried out for defining them. The calculation procedure is programed for easy analysis of barrel response. The influence of barrel vibration on successive uency analysis of the recorded details is carried out. The comparison between muzzle trajectory at different modes of fire. A real time analysis and a frequency analysis of the recorded details carried out.The comparison between both theoretical and experimental results proved the accuracy of the proposed model.
