Research on the Complete Dynamical Model of Tilting-Pad Bearings Considering the Coupling Moving of Shaft and Pads with Turbulent Oil Film

Abstract:

Considering the coupling moving of shaft and pads, a theoretical model for calculating the complete dynamic coefficients of tilting-pad bearing is described in this paper. The model includes the influence of turbulence. Based on this model, the effect of turbulence on journal equilibrium position, pads inclinations, and complete dynamic coefficients is investigated for given load cases. The numerical results indicate that the effect of turbulence is not neglected for higher Reynolds number.
