“…• The forces acting on the casing of the weapon during the firing operation: The forces acting on the weapon and causing the motion of all weapon parts to depend on the type of operation, see [6], are determined based on the knowledge of firing force acting on the barrel, on the gas chamber, and the functional cycle of the weapon. For a portable gas-operated automatic weapon, the definition and analysis of the forces acting on the weapon are described in detail in [6]. Its graph is given in Fig.…”

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.

“…It shows that the cycle of operation and the mathematical model are selected according to the important role in the research process, designing, manufacturing, and improving weapons. Due to this reason, there were documents and research about establishing the model and investigating the influence of the basic factors on the stability of the gun while firing as can be found in research [10][11][12][13][14][15][16][17][18][19][20]. However, documents and research that have comprehensive, systematic, and in-depth analyses on the dynamic of twin-barrel guns still have many limitations and are rarely published, [16][17][18].…”

In this paper, we propose a new twin-barrel gun model for calculating firing on the elastic ground to study the effects of structural parameters on the weapon's performance. This paper intends to provide a theoretical basis and establish a specific model of twin-barrel gun, to build a system of differential equations of vibration, and to determine the rules of vibration of the gun when firing on the elastic ground. The method is used to establish a model of two sets of automatic firing systems by dynamics of a multi-body system. The results of the calculation revealed the instructional significance for improving the vibration performance and increasing the firing accuracy. Experiments were tested out on a 37 mm twin anti-aircraft gun, type 65. The results of the theoretical mathematic model provide a good correlation to experimental data. The maximum amplitude deviation on the horizontal plane does not exceed 8.1%, while in the vertical plane does not exceed 6.4%. The outputs can be used for validation of a dynamic model of a weapon system while firing on the elastic ground, and the procedure can be used as an example of a practical technique and methodology for other weapon systems.
