Research on recoil dynamic characteristics of a gatling gun automatic machine

This paper takes an aerogun automatic machine as the research object, and uses the classical internal ballistic theory to establish a mathematical model for calculating the bore resultant force. The fourth-order Runge-Kutta solution is used to calculate the average pressure-time curve in the internal ballistic and after-effect period. The automatic machine virtual prototype model is established by using the 3D model of the automatic machine and the calculation result of the bore resultant force, and the recoil displacement, recoil velocity and recoil force of the automatic machine are obtained, which provides a theoretical basis for the subsequent research and design of the automatic machine.
