Vibration Behavior Analysis of the Ammunition Belt of the Gas-Operated Machine Gun

Purpose: The paper’s aim is to use the dynamic theory of multi-rigid body systems to establish a dynamic model of the ammunition belt for the gas-operated machine gun. Then, an experimental study is also carried out on the PKMS Kalashnikov 7.62 mm machine gun to verify the reliability of the proposed model. Method: A multi-body mechanical model for dynamic analysis of the ammunition belt is proposed to serve as a foundation for the theoretical calculation problem. In addition, a set of experimental procedures for the PKMS Kalashnikov 7.62 mm machine gun is carried out dynamic analysis problem. Results: The calculation results are compared with the experimental results, including the motion, displacement, and velocity of the ammunition belt and the interaction force between two link joints to confirm the suitability of the proposed model. From here, it can be asserted that our model is an effective one and should be encouraged in research into the dynamics of the automatic machine and the design of the gas-operated machine gun. © 2023, Krishtel eMaging Solutions Private Limited.
