FIELD: physics; testing.
SUBSTANCE: invention refers to mechanical frictional unit test techniques. Mechanical systems of object and model friction mechanical systems (FMS) consist of subsystems. Mechanical subsystems are described by combined similar linearised differential equations, while processes on frictional contact (FC) of "object" and "model" are described by similar mathematical models, regression equation received at natural experiment. Required "object" and "model" parameter ratio is provided. Triboparameters FMS are measured while testing. Friction factor is represented as complex function. It is accompanied with real time control and fixation of contact specific area. Contact temperature is defined by formula.
EFFECT: higher validation.
