Abstract

This paper studied the vibration characteristics of barrel excited by projectile in lauch process of gun. Considering the effect of inertia and the contact condition between projectile and barrel, we simplified the barrel as the Euler equal cross section, and established the vibration equation of barrel which was excited by accelerated projectile, and used the modal analysis method to solve the equation. Through the simulation, we studied the influence of gap between projectile and barrel on the barrel vibration with different motion parameters, eccentric mass and continuous firing of projectile. The results showed that controlling the acceleration of projectile in chamber reasonable, reducing the gap between projectile and barrel and the eccentric mass of projectile, will help to reduce the vibration of muzzle caused by artillery launch. The research results can provide reference for the overall design of gun.
