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

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