The paper includes an analysis of a concept for increasing the service life of 35 mm gun barrels by technological process of self-strengthening. A process of barrel self-strengthening that uses a ballistic method based on technological firings with special ammunition of increased propelling charge is considered. In effect of analytical - numerical studies it was stated that a self-strengthening effect is strictly limited to the cartridge chamber and has a local character i.e. the plastic deformation of barrel’s material includes not more than 30% of barrel wall thickness. The received results indicate that efficiency of self-strengthening provided by the ballistic method is low and in cases of deploying materials with high strength characteristics in barrels it could not bring any benefits at all. |
