“…( 12) is solved in combination with the equations of internal ballistics using Matlab software using the Runge-Kutta method of the fourth-order. One of the parameters used as an evaluation criterion for stability, ability to work safely and reliably is the deviation of the angle of elevation (in the vertical plane) and the deviation of the angle of measurement (in the horizontal plane) [10][11][12]. These parameters were selected to compare and evaluate the proposed dynamic model with the corresponding experimental data.…”

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 determines the firing accuracy and affects the firing efficiency of automatic guns, [1,2]. However, guns can be moved and vibrated while firing, which makes the firing angle of guns deflected after the projectile has left the barrel muzzle and reduced the probability of destroying the target, [3][4][5][6][7][8][9]. The larger the deflection of firing, the smaller finding the probability of destroying the target, [3,5].…”

“…However, guns can be moved and vibrated while firing, which makes the firing angle of guns deflected after the projectile has left the barrel muzzle and reduced the probability of destroying the target, [3][4][5][6][7][8][9]. The larger the deflection of firing, the smaller finding the probability of destroying the target, [3,5]. So, reducing the muzzle vibration can provide the gun with a fine initial ballistic condition and improve firing accuracy.…”

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.

“…Both in terms of materials and in terms of the final shape or dimensions of the finished parts -see [1][2][3][4][5]. In the environment of the defense industry or military technologies [6,7], these technologies find their significant application, as stated, for example, by the authors Kim, Ahn [8] within NATO armies, or Yang, et al [9]. However, it is necessary to know the machine part made by 3D printing technology before using it.…”
