Abstract (English):
In the paper there is described a method of flattening and stabilization of geometrical parameters of long-length parts. The method is based on the formation of a uniform area displacement of an elasto-plastic deformation formed by a bending moment at continuous rotation of a part which results in the occurrence of multi-cycle loading. Because of the action of controlled multi-cycle loading takes place an accumulation and further relaxation of inner stresses. The process of flattening and stabilization of geometrical parameters is described by a simulator showing a tie between geometrical, physic-mechanical and technological parameters. At the heart of a simulator is an energy approach to the description of an elasto-plastic deformation of a part at multi-cycle loading.
