“…Structural vibration modes were analyzed, and changes were made to the turret design in certain locations to strengthen the mounting assembly and obtain better vibration response. Paper [14] describes the task of integrating 12.7 mm hand-held machine guns on a mobile platform and a simulated machine gun stand on a cradle. Based on the determined internal ballistic parameters, the load from firing on the structure and the rotating bearing was calculated using the finite element method.…”

“…When improving gun turrets, researchers mainly study the effect of loads on the structure transmitted from the gun during firing [12][13][14][15]. But the dynamic loads transmitted from the road during movement and loads caused by manipulations with the system affect the turret design and the required power of the drives to a greater extent.…”

During hostilities, ground robotic systems play an important role in minimizing losses of servicemen and suspending the combat capabilities of troops. For firing, robotic complexes are equipped with gun turrets. Researchers are conducting research to improve the performance, reliability and firing accuracy of such turrets. This work describes the design and research of an experimental sample of a ground robotic system, which is equipped with a turret for controlling the position of a machine gun. The description and results of experimental studies of dynamic loads during robot movement at different speeds and road conditions are presented. It was established that the values of the maximum accelerations that must be worked out by the stabilization system during operation for the experimental design of the robot do not exceed 20 rad/s2. The possibility of using counterweights was considered to reduce the torque of the turret guidance drive while reducing the dimensions of the robotic system structure. The description of the experimental module equipped with a control and measurement system and the results of experimental studies on determining the power of the turret drives during the manipulation of the structure are presented. A procedure of dynamic analysis and the results of modeling the movement of the gun turret in the ANSYS software package are presented. The proposed method for designing the structure ensures the determination of the impact on the structure of the complex shape of loads caused by its manipulation, to compensate for the exciting loads when the robotic system is moved over the terrain. With the help of this method, it is possible to determine and minimize the power, and therefore the energy consumption, of azimuth and lifting electric drives at the design stage

“…The studied mechanism is subjected to recoil force of the gun, which can be determined either by measurement using force sensors affixed to the weapon during firing, 20–22 or by estimation from the pressure curve of the exploded powder inside the barrel. 23 It can also be approximated with a half-sinus or exponentially decaying function, with a peak value and action time inspired from the pressure inside the barrel curve. The peak value of the force can be approximated by multiplying the maximum value of the pressure by the bore cross-section.…”

This paper aims to model and design a lightweight U-bracket for two degrees of freedom (DOF) mechanism used to carry a machine gun. The mechanism is called a weapon station or a gun turret and can be mounted on any mobile platform. Due to the movement of the platform and the gun recoil force, the gun turret is subjected to high disturbances. So, to get better performances in terms of distributed efforts, stability and precision, the mechanism has to be optimally designed. The trunnion axis offset corresponding to higher dynamic and structural performance was determined based on probabilistic analysis and finite element simulations. Then, the co-simulation between MATLAB and ANSYS Parametric Design Language (APDL) was performed to get the optimal shape of the U-bracket by minimizing its mass, and maximizing its first natural frequency subjected to maximum stress constraint. To solve this constrained optimization problem, the Multi-Objective Genetic Algorithm (MOGA) technique was used. Through numerical simulations, the proposed approach shows the ability to provide a generic methodology to design the U-bracket of a 2-DOF weapon station efficiently.
