Analysis of Transverse Vibration Modes of a Gun Barrel Subjected to Recoil

Abstract:

This paper focuses on the calculation of modal frequencies and corresponding mode shapes of Gun Barrel by analytical method and the Finite Elements Method. Modal analysis is used to find out natural and succeeding two modes frequencies for transverse vibration. Barrel is considered as a cantilever beam. Recoil of Gun Barrel is incorporated as variation in the length cantilever beam. Increase in modal frequencies due to gun barrel recoil is observed. It is concluded that the transverse vibration of gun barrel coupled with the recoil produces a band of frequencies in each modes. The analysis and results discussed can be used for design and performance evaluation, selection of accessories and attachments of gun systems.
