Analysis of static and dynamic misaligned tilting-pad journal bearings

This analysis deals with the influence of misalignment (static and dynamic) of a tilting-pad journal bearing. Three different isothermal cases were co mpared: the initial bearing clearance and viscosity, the initial bearing cl earance and effective viscosity deduced from a thermohydrodynamic analysis, and the operating bearing clearance and effective viscosity deduced from a thermoelastohydrodynamic analysis. It will be established that increasing the misalignment amplitude and dynamic load and decreasing the lubricant vi scosity and clearance induce large changes in the bearing characteristics ( the minimum film thickness, maximum pressure, axial flow and misalignment m oment).
