Abstract
The friction as competitive process is considered from positions of energy balance equation. Friction surfaces joint work with using this equation is described. As the result of more full evolution of elementary tribosystem the unique nanostructure is formed and the basis of which is one mechanical (nano) quantum. Mechanical quantum represents the least structural form of solid material body in conditions of plastic deformation and under transition tribosystem across the limit activated state by development of selforganazing processes of tribosystem adaptation are formed. Mechanical quantum is dynamic oscillator of dissipative friction structure. Mechanical quantum can be examined as the elementary nanostructure of metal’s solid body. Calculations have shown the number of such mechanical “quanta” (subtribosystems) within the elementary tribosystem’s volume, which is close to the safe number of fatigue cycles. Their joint rotationary-oscillatory behavior in relation to each other has determined the dynamic dissipation energy effect. Calculative model for dynamic oscillator of friction dissipative structures is offered.
