On the basis of analysis of factors affecting the stability of firing frequency, a dynamic model of the automatic mechanism in a machine gun is established. The paper studies the influence of the coefficient of friction, the recoil spring rigidity and the pressure impulse of the gas chamber upon the firing frequency stability. Tests were performed on the influence of the recoil spring rigidity and the pressure impulse of the gas chamber by experiments, and reached at conclusions that gave laws of the coefficient of friction, the recoil spring rigidity and the pressure impulse of gas chamber. Technical proposals are given on improving the firing frequency stability. These results provide a gist on controlling the gun's firing frequency stability.
