Principles and Methodologic Peculiarities in the Research of the Tribosystem with Sliding on Translation Cyclic Movement

Abstract

The work presents methodological aspects of behavior research in the cyclical slip tribosystems regarding the dynamics of contact processes. Taking into account the fact that in the contact, processes of various origins (mechanical, thermal, hydrodynamic, electrical, and chemical) take place and superpose, and these processes influence each other reciprocally, their dynamics may be evaluated only by using dynamic measurement systems. A non-linear mechanical oscillator with an elastic element and dissipation is used as a dynamic system. The evaluation of the tribosystem’s behaviour is made after processing and using methods of non-linear dynamics of data from time series, obtained experimentally and reduced to the coordinates of the oscillator. The suggested method allows correct evaluation and prediction of evolution of the tribosystem
