Abstracts

Zernin M.V. Techniques of estimation of operability of sliding bearings developed at the departament "Dynamics and strength of machines" BSTU. Described developed at the de-partment "Dynamics and Strength of Machines" Bryansk State Technical University computa-tional and experimental methods of estimation of efficiency and durability of bearings in the cri-teria of interaction and surface damage. Describes the method of calculation of the hydrodynam-ic and contact pressures and stresses, fatigue processes modeling techniques in anti-friction layer and the different types of wear of its surface. The review of publications of staff of chair is actu-ally provided in the central magazines on this subject and the directions of further development of offered approaches are specified.
