DOI 10.1109/icamcs62774.2024.00010
Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

A new generalized dynamic model of the rotor system has been developed, which considers the interconnected oscillations within the “rotor - weakly conductive fluid - foundation” system. This model incorporates various factors, including linear eccentricity, movements of the fluid and rotor, frictional forces, base vibrations, rolling bearings and their nonlinear properties, and the magnetic field's influence on the fluid. The motion equations for this system were formulated and solved analytically. The analysis of the system's oscillations revealed key features of its dynamics. The frequencies and amplitudes, which significantly influence the system's dynamic behavior, were investigated, and determined.
