Investigation of the Mechanical Dynamics of the PRV-1 Machine Gun Installed on a Combat Robot

This paper investigates dynamics of a PRV-1 machine-gun mounted on a combat robot using multi-body mechanics and finite-element approaches. A model quantifies gas pressure forces on the barrel base and piston face, including a damping mechanism. Structural dynamics were solved by two methods: differential equations of motion solved in Maple and dynamic equivalence modeling in MSC Adams. Results – presented as time histories of displacement and velocity for the bolt carrier, gun body, and robot – agree methods and match observed operational behavior. The analysis demonstrates the critical role of the damping system in reducing recoil and improving accuracy, identifies key dynamic parameters for optimization, and provides a scientific basis for designing and optimizing weapon systems on future platforms, as well as guiding future experimental validation efforts.
