Kinetic Coordination Analysis for Feeding and Ramming Mechanism of a Type of Automatic Gun

In order to find out design method and theory basis of feeding and ramming mechanism of a type of automatic gun, based on operational principle of the mechanism, kinetic coordinative principle was proposed by means of analysis for structure and kinetic characteristics. By use of momentum theorem and Lagrangian equation, kinetic characteristics of feeding mechanism of automatic gun under the conditions of with and without belt feed torsion spring were calculated, the important role of torsion spring in coordinative action was emphatically analyzed, and the reference usage of technical measures in the design of automatic gun body and the feeder were discussed. The obtained conclusion had an important reference role in the research and development of gas operated driver of the automatic gun.
