RESEARCH INTO THE INFLUENCE OF SELECTED PARAMETERS ON CRITICAL SPEED OF THRUST BEARING WITH THE MAGNETORHEOLOGICAL FLUID
Journal Title: Tribologia - Year 2019, Vol 284, Issue 2
Abstract
Magnetic fluids are substances with a complex physicochemical composition. The unique properties of these substances are based on the possibility of reversible, almost immediate, changes in their rheological parameters, as well as changes in the flow direction due to the magnetic field. These properties allow the development of machines and devices with operating parameters that can be changed by the magnetic field. The range of the fluid property changes depends on its composition, magnetic field parameters, operating conditions, and the method of fluid deformation. The paper presents the results of research into the influence of selected parameters on the critical speed of thrust sliding bearings. These parameters include the magnetic and physical properties of magnetic fluids, the value of the magnetic induction, the fluid volume in the working gap, and the temperature. The results of the conducted research indicate a significant effect of the magnetic field gradient on the critical speed value.<br/><br/>
