STUDY OF THE OSCILLATION OF THE GUN BARREL UNDER THE IMPACT OF THE WARHEAD MOVING INSIDE THE BARREL

Abstract

This study presents the dynamic interaction between a cannon barrel
simulated as an Euler-Bernoulli cantilever beam and a warhead that
accelerates during firing. The interaction is modeled using a finite element
method (FEM) that takes into account the inertia, acceleration, and gravity
forces of the projectile. The article evaluates the effects of the mass, velocity,
acceleration of the warhead and the launch angle when the bullet exits the
barrel on the dynamic change of the barrel. By using the FEM method, we can
approximate the barrel's oscillation, the factors affecting the barrel's
oscillation at the moment the bullet exits the barrel. Research results help
designers have more information to calculate the accuracy of fire of weapons
and help shorten the testing process.
