EFFECT OF TIP MASS ON TRANSVERSE VIBRATION MODES OF A GUN BARREL SUBJECTED TO RECOIL

This paper focuses on the calculation of modal frequencies and corresponding mode shapes for transverse vibration of Gun Barrel. The Barrel is considered as a cantilever beam. Recoil of Gun Barrel is incorporated as variation in the length cantilever beam and transverse vibration produces a band of frequencies in each mode. Further the effect of tip mass is considered and concluded that the band of frequency is shift to the lower side in each mode. The analysis and results discussed can be used for design and performance evaluation, selection of accessories and attachments of gun systems.
