Stribeck curve

The Stribeck curve illustrates the relationship between lubrication and friction in mechanical systems. It shows how friction changes with varying speeds and lubricant conditions. Initially, at low speeds, friction is high due to solid surface contact. As speed increases, lubrication improves, reducing friction until a minimum point is reached. Beyond this point, as speed continues to increase, friction stabilizes and can even rise again with changes in lubrication type. Understanding this curve helps engineers design better machinery, ensuring smooth, efficient operation and longevity of components by selecting appropriate lubricants for specific conditions.
