METHOD OF DYNAMIC MONITORING OF FRICTION MOBILE SYSTEMS Russian patent published in 2014 - IPC G01N3/56 

FIELD: testing technology.

SUBSTANCE: invention relates to methods for testing friction units of mechanical systems. Essence: assessment of condition of tribosystem is carried out by the analysis of integral estimates (dissipation function, degree of dissipation, energy losses of the friction system brought to the outlet, the squared absolute value of the coherence), the amplitude stability margin and phase of amplitude-phase-frequency characteristics. On the physico- mechanical models of the full-scale systems the gathering of database of tribotechnical, tribospectral and output characteristics is carried out, at that the change of these estimates by a predetermined amount of peak factor determines the sensitivity of the automatic control systems of the tribosystem or the automatic control systems of parameters of the tribosystem and serves as identification feature of transition from one steady state to another.

EFFECT: ability of short-term or long-term prediction of the dynamic state of the mechanical system and, in particular, the frictional contact with the ability to control its dynamic characteristics.
