Self-organization and evolution in dynamic friction systems

The dynamic features of the friction process contacting pairs affect their durability and functional suitability. There-fore, problems dynamics vibrational activity always attract attention researchers in field tribology. It is known that self-organization processes take place during friction, such as formation selective transfer phenom-ena equilibrium roughness. But studies do not into account changes properties system its functioning. primary sources are energetic nature, but relationship these phenomena with has been explained, modeling yet performed. paper presents results experimental mathematical evolutionary due to power irreversible transformations energy input zone, which characterizes goal research. In order achieve goal, deals a combination analysis system, stability, manifolds formed vicinity equilibrium. shown proposed models integro-differential functionally coupled equations describe self-organization. Examples given restructuring including bifurcations attracting sets deformation displacements along trajectory forces work. briefly study vibration characteristics development wear by example two systems: steel-brass steel-glycerin-brass. new establish naturally work forces. These determined change parameters coupling attractive displacements. experiments show measurement available for estimation some coordinates allows one solve problem non-decoupled monitoring state units also opens ways improvement units.
