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 MATLABregistered and verified by modal impact testing. Modal impact testing was done for the barrel alone and for three different muzzle brake vibration absorber configurations. Additionally the gun was fired with and without the absorber to determine its performance. Significant reduction in shot dispersion was observed.
