Modeling and Analysis of Floating-Ring Bearing ThermoHydrodynamic Parameters for Advanced Turbo-Rotor Systems
Journal Title: American journal of Engineering Research - Year 2017, Vol 6, Issue 10
Abstract
This work presents a detailed analysis and modeling of floating-ring bearings (FRBs) for predicting their dynamic-force coefficients, thermo-hydrodynamic characteristics, and instability behavior. The mathematical model is based on modified Reynolds equations combined with thermo-viscous and centrifugalforce effects. The force coefficients are obtained from the non-linear integration of film pressures using Sommerfeld integrals. The results display the impacts of film properties and journal speed on load capacity, rotor eccentricity, viscous-friction, and whirl frequency. Also, the relationship between FRB geometry (radius ratio, R2/R1; slenderness, L/D2; and clearance ratio, C2/C1) and load capacity, oil-flow, and heat dissipation are established. Predictions agree with test-data.
