The deformation mode of the brake pulleys of the draw-works at multicells origin and development of microcracks

Journal Title: Проблеми тертя та зношування - Year 2016, Vol 70, Issue

Abstract

We’ve Illustrated the deformation mode of the brake pulleys of the draw-works at multicellsorigin and development of microcracks, based on the analysis of factors and dissemination offractals, acting on the working surface of the rims. There were the following tasks: to evaluatethe condition of the kinetic of the working surface of the metal element in the frictional interactionwith the position of fractals; to perform analysis of multicells origin and development ofmicrocracks in the rim of the brake pulley; to establish patterns of change in the stress state ofthe brake pulley
