Abstract

To analysis of contact interaction between barrel and projectile, its finite element calculation formulas were deduced on the base of contact theory. By using the new method and finite element model, the contact interaction between barrel and projectile of a rifle was calculated. The calculation results show that the barrel and projectile were plastic deformation, especially the equivalent stress of projectile has been in strength limit region, and this is the main reason for embed copper during firing. So, the structure of barrel rifling and projectile should be optimized. The optimization process can be guided by the new method, and a computing platform for the process was provided by the established model.
