Lubrication of Sliding Bearings for Hydropower Applications

The influence of pad facing material on hydrodynamic lubrication in tilting-pad thrustbearings is investigated in terms of pad and oil-film temperatures and oil-film thickness. Two tilting-pad thrust bearings are examined: one with babbitt pad facing, the other with a layer of a PTFE based composite material. Frictional torque, pad, collar and oil-film temperatures and oil-film thicknes...

Thermohydrodynamic Characteristics of Journal Bearings Running under Turbulent Condition

A thermohydrodynamic (THD) analysis of turbulent flow in journal bearings is presented based on the computational fluid dynamic (CFD) techniques. The bearing has infinite length and operates under incompressible and steady conditions. In this analysis, the numerical solution of Navier-Stokes equations with the equations governing the kinetic energy of turbulence and the dissipation rate, couple...

Control of structures with friction controllable sliding isolation bearings

A friction controllable sliding isolation system was developed and experimentally and analytically investigated by Feng et al. (Feng, Q., Shinozuka, M. & Fujii, S. A. friction controllable sliding isolation system. J. Eng. Mech., ASCE, 1993, 119(6), in press), the control algorithm having been developed based on a key assumption that the structural motion is always in the sliding phase. However...

On the Characteristics of Misaligned Journal Bearings

Journal bearing misalignment arise generally from the shaft deformation under load, deflection of the shaft, manufacturing and assembly errors, improper installation, and asymmetric loading. During operations, misalignment has a considerable effect on the static and dynamic performances. It could cause wear, vibration and even system failure. In this article, a literature review of misalignment...
