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.
Tribology is the science and engineering of understanding friction, lubrication and wear phenomena for interacting surfaces in relative motion. It is highly interdisciplinary, drawing on many academic fields, including physics , chemistry , materials science , mathematics , biology and engineering . [ 1 ]
Richard Stribeck carried out studies in the field of tribology, focusing on friction in lubricated sliding contacts, such as journal bearings.His work lead to the development of the Stribeck Curve, a fundamental tribological concept that shows how operation conditions (in particular normal load, lubricant viscosity and lubricant entrainment velocity) influence the friction coefficient in fluid ...
Tribology is the science and engineering of interacting surfaces in relative motion. It includes the study and application of the principles of friction, lubrication and wear. It includes the study and application of the principles of friction, lubrication and wear.
Such understanding also drastically changed the direction of undertakings in tribology. The works of Bowden and Tabor yielded several theories in contact mechanics of rough surfaces. The contributions of J. F. Archard (1957) [ 12 ] must also be mentioned in discussion of pioneering works in this field.
[1] [2] He also made significant contributions to the field of tribology. The functional relationship between the coefficient of friction and the product of sliding speed and viscosity divided by the normal load (well known as the Stribeck curve ) was experimentally explored by Adolf Martens in 1888, long before Richard Stribeck made his ...
When two consistent, unlubricated surfaces slide against each other, there is a specific, predictable amount of friction that occurs. This amount increases as velocity does, but only up to a certain point. That increase generally follows what is known as a Stribeck curve, after Richard Stribeck. On the other hand, if the two surfaces are ...
Later, Nikolai Pavlovich Petrov, Osborne Reynolds and Richard Stribeck supplemented this understanding with theories of lubrication. Deformation of solid materials was investigated in the 17th and 18th centuries by Robert Hooke , Joseph Louis Lagrange , and in the 19th and 20th centuries by d’Alembert and Timoshenko .
