SURVEY OF STRESS AND DEFORMATION OF A VIETNAMESE-MADE 12.7mm NSV GUN BARREL DURING FIRING

Abstract

The types of weapons designed and manufactured by Vietnam require thorough investigation of the loads on the barrel and the components of the gun when fring. This article applies specialized software ANSYS WORKBENCHES to investigate the stress and deformation of the barrel during single and automatic fring. So that, the load on the barrel wall includes both thermal and pressure loads. There results are used to assess the strength and lifespan of the gun barrel during fring. The 12.7mm NSV gun in Vietnam is no exception; it is necessary to study the stress and deformation of the barrel under temperature and pressure loads when fring single shots or automatic shots. This result is used to assess the strength and lifespan of the gun barrel during fring. Recommendation to choose the appropriate shooting mode.
