Effect of an Internal Impact Balance Mechanism on the Perceptible Recoil of Machine Gun

Abstract

In order to reasonably reduce the perceptible recoil of firearms, and design a recoil reduction device that can be commonly used in automatic rifles, semi-automatic rifles, and machine guns, a balancing mechanism for recoil reduction technology was proposed in this paper. With the perceptible recoil generated by the impact from automat to the balance mechanism as the objective function, the parametric analysis of the mass of the balance weight and the spring stiffness of the balance mechanism was conducted. The analysis showed that the influence of the mass of the balance weight on the reduction of the perceptible recoil of the balance mechanism is obviously greater than that of the spring stiffness of the balance mechanism within the allowable ranges of the two factors. The research results provide a reference for gun recoil reduction technology.
