Effect of Bearing Elastic Deformation on the Turbulent Thermohydrodynamic Lubrication of Misaligned Plain Journal Bearings

This paper investigates the effect of bearing shell elastic deformation on the steady state behavior of misaligned journal bearings. Performance trends of elastic and rigid bearings with different degree of misalignment (Dm) have been compared. Bearing shell elastic deformation, thermal effects, pr...
