Adaptive Gun Barrel Vibration Absorber

Abstract

Gun barrel vibrations lead to dispersion in the shot patterns. Thus, reducing these vibrations should lead to increased accuracy. Since the muzzle is the anti-node for all vibration modes and its vibrations have the greatest effect on shot dispersion, it is the obvious location to attempt to dampen the vibrations. A model of the gun barrel was created in MATLAB(registered) and verified by modal impact testing. Modal impact testing was done for the barrel alone and for three different muzzle brake vibration absorber configurations. Significant reductions in muzzle vibrations were achieved using the vibration absorber. Methods of making the vibration absorber adaptive and models of such a system are presented.
