Methods and Means of Reducing Energy Load and Hydrogen Wear of Friction Pairs of the Band-Shoe Brake of the Drilling Winch

Abstract

In the materials of the article, the issues are considered in relation to the problem being solved: the construction of crystal lattices of metals and their parameters; assessment of the state of atoms in the crystal lattice of a metal from the standpoint of molecular dynamics; stress-strain state of brake discs and centers of hydrogen wear of their working surfaces. In the study of a metal friction element, a model of a multilayer atomic structure in the form of a bellows was adopted, which, under the action of pulsed specific loads, compresses its corrugations. When the load is removed, the multilayer atomic structure expands due to the elastic forces. It was found that the rate of the process of compression is hundreds of times higher than the rate of the process of expansion of a multilayer atomic structure.
