The stability of automatic firearms during discharge is a crucial element that influences precision and safety. Current research often overlooks the synergistic influences of the shooter and the firing environment on weapon dynamics. This research seeks to create a dynamic model for a gas-operated pistol affixed to a bipod, considering the interplay of the shooter, the ground, and the weapon system. The dynamic model is constructed using the Lagrange theorem and the principles of multi-body system dynamics. An elastic and viscous damping connection is implemented to model the interaction between the shooter, ground, and weapon. The bipod-mounted UK-59 machine gun serves as a case study for dynamic simulations. The simulation findings precisely replicate the actual motion of the handgun and validate adherence to the manufacturer’s design specifications. The investigation underscores the influence of structural characteristics on firing stability. The suggested modeling methodology offers a dependable foundation for the evaluation, calculation, and design enhancement of automated weapon systems. The findings are significant for instructional applications and for enhancing weapon design and firing stability.
