TORSIONAL OSCILLATIONS OF A GUN BARREL

Abstract

An analysis is presented of the torsional oscillations of an artillery barrel when subjected to the moment of an accelerating projectile. A modal series is obtained, the coefficients of which are the time dependent generalized coordinates. OR PURPOSES OF OBTAINING NUMERICAL RESULTS( THIS SERIES WAS TRUNCATED at two terms; the subsequent system of ordinary differential equations was programmed for the analog computer. Graphic solutions are given for several values of the barrel size to projectile mass ratio.
