Design and Validation of a Gun Barrel Vibration Absorber.

Abstract

This paper presents an applied method for the optimal design of passive vibration absorbers to reduce terrain induced vibrations of tank cannons. The method uses a finite element model of the cannon. The design is optimized by assigning a scalar cost function to the frequency response of the modified barrel. The results indicate that the peak amplitude of the frequency response of a 1,500 Kg barrel may be cut in half by an appropriately tuned 20 Kg absorber. Experimental validation of the results using modal impact testing are shown.
