In this work, a harmonic oscillator with elastic elements is adopted as a model of a mechanical system sensitive to various force disturbances. The developed physical and mathematical models for the interaction of the oscillator with the tribosystem model formed the basis for the creation of a method and a set of experimental tools for assessing the tribological state of the contact and the behaviour of the sliding tribosystem under dynamic operating conditions. For this purpose, an original installation was designed and built with a specially designed test chamber using a harmonic oscillator as a sensitive unit. The installation is equipped with a specially developed measuring system for monitoring the state of the tribomodel and the oscillator, implemented using experimental data collection tools (products of National Instruments). According to the methodology, specialized software has been developed using LabVIEW, which allows for the collection, processing, and storage of experimental data in large volumes and with high productivity.
Keywords: tribosystem, friction force, model, dynamic regime, software.
