Effect of Some Structural Parameters on Firing Stability of Shooter-Weapon System

Abstract

This article presents a method to establish the dynamic model of the Shooter-weapon system when firing based on Lagrange’s theorem and the theory of multibody system dynamics, in which the influence of the human body was taken into account. In the dynamic model, the influence of the gunner is solved by using elastic-damping links in the x, y and z axes. The dynamic model is created for a portable gas-operated submachine gun and contains three solids with seven degrees of freedom. The 7.62 mm AKM submachine gun has been used for the model simulation and experimental verification. The dynamic simulation was conducted and then the results were compared with the corresponding experimental data. The model simulation results are very close to the experimental results. This study aims to survey the influence of various parameters on gun stability in the shooting. It is possible to apply these results to portable automatic guns.

Research on the Influence of Some Factors on the Departure Angle of Warheads When Firing a Series

“…In the world, there have been many studies on the factors affecting the projectile's departure angle such as the influence of the semi-link phase [3], and the influence of the bullet structure [4][5][6], some studies have proposed the law of barrel wall temperature and its influence on the projectile's departure angle [7][8][9][10]. In general, previous studies mainly focused on the influence of the shot on the oscillation of the barrel, but no research has mentioned the swing of the range mechanism on the angle of departure of the projectile.…”
