Obtaining corrugations according to the method of their manufacture on the inner surface of a cylindrical shell

Abstract

The operation of applying riffles by local plastic forming on the inner surface of a cylindrical shell with the help of a working mandrel with wedge protrusions on the working surface is considered. The results of computer simulation are presented, and a comparison is made with the known reduction corrugation method. A significant decrease in the technological force in the process of corrugation and removal of a cylindrical shell using a new method has been established
