Numerical research on ablation and wear of the artillery barrel based on UMESHMOTION user‐defined subroutine

Abstract

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.

Application and Prospect of Wear Simulation Based on ABAQUS: A Review

“…In addition to the applications of wear simulation in the POD test, gear wear, and implant wear, wear simulation is also applied in many other fields, which can be seen in Figure 10, such as the wear of seal [123,124], chain [125], tire [126], cam [127], artillery barrel [128], pump [129], metal wire [4] and so on. However, it can be observed that regardless of the field where wear simulation is applied, the main functions of wear simulation are wear profile prediction, service life prediction, and wear mechanism auxiliary analysis.…”

Frictional Study on 30CrNi2MoVA Steel Based on Experiments and Finite Element Simulation: Wear Prediction

“…The implementation steps for dividing the adaptive grid include the Sweeping and Advection processes. In the ball-disc wear model presented in this paper, ALE acts on the contact wear surface and calculates the wear amount using the UMESHMOTION subroutine [31][32][33][34][35]. After each incremental step of stress update, the ALE algorithm is applied to the elements within the ALE scope.…”
