Determination the Stress and Deformation of the Cannon Barrel When Fired

Abstract

This paper presents a calculation process of the stress field of the 130M46 cannon barrel when firing under the load of gas pressure and temperature. The paper will focus on calculating the stress of a barrel and solving some disadvantages of previous methods using the finite element method and the simulation tools of the CFD software. The calculation results are the stress and deformation parameters of the barrel such as normal stress, tangential stress, average stress, radial deformation, tangential deformation, and total displacement. These stress values are determined when firing 1 shot and 8 consecutive shots to determine the allowable durability limit of the gun barrel material. The result of this research can be used to study and analyze some similar technical issues in weapons.
