Study of the characteristics of a sliding bearing under dynamic loading

The article discusses the prerequisites and the process of creating an experimental bench for the study of external electromagnetic effects on rotor-bearing units in the work process. The control systems of the experimental setup and the electromagnetic device are presented, the latter is made in the form of 4 paired orthogonally located electromagnets. The percussion device can operate in a programmable mode. Flexible variation in speed and magnitude of the impact (according to a predetermined law of change) allows you to cover a wide range of possible external influences on the rotor unit. The tool for the automatic control of installation modules, as well as the collection and processing of experimental data, is software developed in the LabView visual programming environment. The drivers for matching the frequency converter and the controller, as well as all the software for the operation of the information-measuring system, the experiment and data processing, were written in the graphic programming language.
