Influence of Barrel Wear and Thermal Deformation on Projectile Ramming Process

Popis výsledku v původním jazyce

This article deals with barrel wear and barrel thermal deformation of heavy guns and their influence on the ramming process. Barrel wear was measured on 125 mm smooth tank cannon barrels. Barrel thermal deformation and the ramming process of APFSDS projectiles was calculated using ANSYS Workbench software utilising 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 calculation and simulation results were used as a theoretical background for: evaluation of the influence of both barrel thermal deformation and barrel wear on ramming process characteristics; evaluation of firing safety of guns having worn barrels according to the Czech Defence Standards; evaluation and specification of barrel quality of self-propelled howitzers and tank cannons with respect to the ramming process.
