Zakharchenko M. Modelling of processes of friction and wear in direct and reverse tribosystems in the conditions of boundary lubrication

The dissertation directed at methodology development of modeling the wear rate and friction coefficient of direct and reverse designs of tribosystems in the conditions of boundary lubrication. A method of determining the actual characteristics of the contact surfaces of friction materials in the interaction tribosystem. Using the actual characteristics of the contact and tribological properties of the lubricant developed a mathematical model of the distribution of the speed of the dissipation between triboelements of tribosystem. Has been further developed the concept of material compatibility in tribosystem – the quality factor of tribosystem, which characterizes the ability of conjugated materials tribosystem (lubricating environments and rheological properties of the material structure of the movable and stationary triboelements) converting the work friction forces into heat energy, thereby discourage energy reserves in the surface and subsurface layers of triboelements. A method of modeling capacity wear rate and friction losses of direct and reverse designs of tribosystems. The technique allows the design stage of new cars through calculations select the optimal combination of materials options, lubricating environment, surface treatment of friction and calculate the projected resource in tribosystems.
