Lubricants: Introduction to Properties and Performance
Shetland's Oil Era: Phase Two
Friction is principal cause of wear and energy dissipation. Improving friction control can make a substantial savings. It is estimated that one third of the world�s resources in present use is needed to overcome friction in one form or other. Lubrication is effective means of controlling wear and reducing friction. Tribology is field of science, which applies an operational analysis to problems of great economic importance such reliability, maintainability and wear of technical equipment ranging from household appliances to spacecraft ref.: Chemistry and Technology of Lubricants read for free.

The results show that the shape of asperities has significant influence on pressure distribution over the entire range of contact lengths. It is also shown that the elastic coupling of adjacent asperities and asperities of different scales increases the nonlinearity of the contact interaction , source: Bearings: A Tribiology download here

This has played a fundamental role in the development of new low-emission, low-friction engine oils
online. Such effects are clearly important in boundary layer lubrication [6]. More recently we have begun to look at the dynamical response of the liquid squeezed between two surfaces i.e. at the local viscosity [7]. The data appear to show that the viscosity of the solvation layers nearest the surface is higher than that of the bulk even for tip radii ~100 nm, although more work is required here because of the difficulty in accounting for the hydrodynamic damping of the AFM cantilever itself
download. March 28, 2016 In the current study, in order to obtain a thick film thickness under zero entrainment velocity at low surface velocity, the effects of ambient viscosity, pressure–viscosity index of the lubricant, and the surface waviness are investigated numerically based on a thermal elastohydrodynamic lubrication mathematical model
online. These enhancements are in terms of increase of the critical mass parameter and decrease for the whirl frequency ratio. Also, by comparing the two dynamic analysis methods, it is seen that the results of linear model are more conservative in different investigated cases. The results of nonlinear analysis reveal that by changing the preload factor the dynamic responses of the lobed bearings appear in different manners Surfactants in Tribology, 2 Volume Set

Stribeck studied different bearing materials and aspect ratios D/L from 1:1 to 1:2. The maximum sliding speed was 4 m/s and the geometrical contact pressure was limited to 5 MPa. (These operating conditions were related to railway wagon journal bearings.) The reason why the form of the friction curve for liquid lubricated surfaces was later attributed to Stribeck, although both Thurston and Martens achieved their results considerably earlier, (Martens even in the same organization roughly 15 years before), may be because Stribeck published in the most important technical journal in Germany at that time, Zeitschrift des Vereins Deutscher Ingenieure (VDI, Journal of German Mechanical Engineers) , source: Tribology 1970: Convention read online

However, such a mechanism still exists on a microscopic level due to roughness. It is common to translate roughness into a variation of fluid film thickness which in turn yields a hydrodynamic pressure distribution resulting in a net hydrodynamic lift Friction and Wear Transitions download for free
