Weblubrication mechanisms one convenient method is Stribeck curve. (Refer Slide Time: 00:49) Stribeck curve is basically a curve between coefficient of friction and bearing number. Bearing number can be defined as sliding velocity, what we are talking about the relative sliding velocity lubricant with viscosity per unit load. WebMar 1, 2007 · This paper describes a mixed elastohydrodynamic lubrication (EHL) model for finite length elastic journal bearings.The finite element method was employed to discretise the coupled system of 2D–3D Reynolds-structure equations and to compute Stribeck curves at constant load. As underrelaxation strategies have been found to be insufficient for an …
