A new method of finish-strengthening cylindrical bushings by transverse burnishing with flat plates is considered. Using the ANSYS software package, the stress-strain state of the cylindrical bushings under transverse rolling by flat plates is defined. The plastic deformation and the shape accuracy of the bushings after the transverse burnishing are determined. The distribution of residual stresses in the cross section of the bushings is obtained. The influence of the degree of percentage reduction on the formation of residual stresses of the bushings after transverse burnishing is analyzed. It is established that the wall thicknesses, the degree of percentage reduction and the number of the billet rotations are the main factors affecting the stress-strain state of the bushings. The results of the study allow the authors to recommend the proposed method of transverse burnishing by flat plates for introduction into the technology of manufacturing cylindrical bushings with a certain wall thickness.
