Abstract
The hydrodynamic theory of lubrication for dynamically loaded journal bearings is extended to elastico-viscous lubricants. The Rivlin-Ericksen equation is assumed for the lubricant, with the second-order terms representing cross-stresses and stress relaxation. The orbits of the journal center deviating from its static equilibrium position were calculated for constant and periodic load conditions. A considerable improvement, compared with the Newtonian solution, is obtained. This is evident from the diminished eccentricity of the orbits and the faster damping of disturbances.Keywords
