Abstract

The gun barrel temperature field formed by the thermal shock of the gunpowder gas with high temperature and high pressure on the barrel of a new type of medium-caliber cased telescoped ammunition machine gun during firing is simulated and analyzed. It is found that a sealing structure designed on the machine gun has good sealing performance, so the temperature field of this new machine gun barrel can be analyzed and calculated by the conventional finite element method. The finite element model of the gun barrel is established by Ansys software, and the heat transfer process of the gun barrel is simulated based on the theory of nonlinear transient thermodynamics, to obtain the distribution law of the temperature field of the gun barrel under different firing modes in the three calculated cross sections, which will provide the related theoretical basis for the prediction of the life of the gun barrel of this new type of machine gun as well as for its optimization design.
