Stribeck's equation
http://article.sapub.org/pdf/10.5923.j.mechanics.20130301.04.pdf In general, there are two approaches for the calculation of Stribeck curve in all lubrication regimes. In the first approach, the governing flow and surface deformation equations (the system of the Elastohydrodynamic Lubrication equations ) are solved numerically. Although the numerical solutions can be relatively … See more The Stribeck curve is a fundamental concept in the field of tribology. It shows that friction in fluid-lubricated contacts is a non-linear function of the contact load, the lubricant viscosity and the lubricant entrainment speed. … See more Richard Stribeck's research was performed in Berlin at the Royal Prussian Technical Testing Institute (MPA, now BAM), and his … See more For a contact of two fluid-lubricated surfaces, the Stribeck curve shows the relationship between the so-called Hersey number, a … See more

The equation of motion for the system can be formulated as mx€ ¼ kðx 0 xÞ F, (1) where m is the mass of the moving body, x the position of the body, x 0 the independent position of the wall, k the spring constant, and F the friction force. The friction force on the body acts in the opposite direction to the sliding velocity of ... WebStribeck Performed several experiments to understand the effect of COF, V and Pressure He also explained the regions of transition and divided his graph in different Lubrication regimes To understand the Pressure, Load and velocity combined effect on FFL we can use the knowledge of Reynold’s Equation 7.

(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.
