STABILIZATION OF RESIDUAL STRESSES TO IMPROVE THE ACCURACY OF PARTS

The results of studies on stabilization of residual stresses in areas of highly loaded parts that are difficult to process, obtained by various methods, including by assembling with non-removable fixed and movable joints, are shown. The mutual influence of various types of hardening on the deformation of parts is revealed, and ways to control the hardening modes by vibration effects that can be caused by controlled electromagnetic pulses with the imposition of an electric field are shown. Ways of controlling mechanical impulses to strengthen the surface layer are proposed a layer with equalization of internal stresses of parts and their combinations obtained from fragments, which allowed not only to align them and reduce the errors of production facilities. Combined technological processes of pulse stabilization of the geometry of workpieces have been developed due to the joint controlled action of mechanical and magnetic factors. The possibilities of extended use of research results in mechanical engineering, including in the manufacture of high-pressure vessels, technological equipment and parts operating under heavy loads, are substantiated.
