Mechanics of contact interaction during grinding of steels

Autor: T. N. Ivanova, V. B. Dementyev, O. V. Zakharov

Publikováno v: PROCEEDINGS INTERNATIONAL CONFERENCE “PROBLEMS OF APPLIED MECHANICS”.

The article deals with problem of contact interaction between the diamond grinding tool and the surface of the part. As a result of the research, we have obtained actual areas of contact for the cases of elastic contact, plastic contact and elastic-p

Influence of residual stresses on the precision of crawler tracks’ hollow fingers under high-temperature thermomechanical treatment with deformation by screw cogging

Autor: V. B Dementyev, A. D Zasypkin

Publikováno v: Traktory i sel hozmashiny. 79:52-54

Residual stresses formed under screw cogging deformation in the high-temperature thermomechanical treatment mode were considered. They facilitate the increase of hot-rolled metal pipe precision up to precision level of cold-calibrated rolled metal by
