Evaluation of projectile ramming process in new and worn smooth barrels of guns

Original language description

This article deals with the influence of barrel wear and barrel thermal deformation of tank cannon on the ramming process. Barrel wear was used as input data from measuring on 125 mm smooth tank cannon barrels. Barrel thermal deformation and the rammingprocess of APFSDS (Armor-Piercing Fin-Stabilized Discarding Sabot) projectiles were calculated using ANSYS Workbench software utilizing the Finite Element Method (FEM). The ramming process calculation was done for two case scenarios: the first case was for a new barrel deformed by barrel thermal effects from firing; the second case was for a worn barrel influenced by the same thermal effects. The reaction force as the most important standardized factor used to evaluate the effect and safety of the ramming process is verified by experiment performed on the above mentioned 125 mm weapon system. The calculated results are reasonably compatible with the experimental results. The research results also provide a background for the state-of-th
