【 摘 要 】

The results of computer simulation of bending stiffness of cylindrical part are presented. The effect of residual stresses on the maximum bending is considered. It is established that the formation of residual stresses in the surface layers of a certain thickness have a positive effect on increasing the rigidity of the cylindrical pieces. The influence of the degree of relative deformation with the covering surface plastic deformation on the flexural rigidity of long shafts is determined. It is established that the degree of relative deformation in the range from 0.4 to 1.0% has a positive effect on the flexural rigidity of the shafts. The process in question can be implemented without the use of environmentally hazardous lubricating cooling technological means, which makes it possible to attribute it in the future to one of the types of green mechanical processing technologies.
