During the firing process, the gun barrel bears the thermal and chemical erosion of high‐temperature gunpowder gas and the wear of the rotation band. The forced cone tended to the most severely worn part of the barrel, which directly affects the life of the barrel. Combined with the erosion test and wear test of gun steel materials, this research studied the forcing cone of a medium caliber naval gun barrel. With the commercial finite element software ABAQUS as the platform, we took advanced adaptive mesh method combined with secondary development technology. This method used in our study in order to better realize the numerical simulation of the radial erosion wear of the forced projectile cone in the continuous firing environment. At the same time, we compared the numerical simulation with the actual firing test data, and proposed a new calculation method of barrel life. In conclusion, the results of this study showed that this method can better calculate the radial erosion wear of the forced cone, and provide guidance for improving the life of the gun barrel in the future. This article proposed a numerical method to calculate the ablation wear of the barrel. The research content of this article can be used to predict the life of gun steel materials in actual combat use. It includes secondary development technology, experimental verification and other steps, and the article structure is complete. This research is currently leading in the field of gun steel research.
