4. EHD linear contact lubrication
When the cylinders in contact are subjected to a high load, elastic deformation of the masses occurs. This is known as elastohydrodynamic lubrication (EHD).
4.1 Elastic deformation of solid bodies in contact
-
Hertz theory
Hertz theory can be used to calculate the elastic deformation and pressure field in the contact . Under load, the point or linear contact becomes a contact with an elliptical or rectangular surface. This surface is very small, resulting in a high contact pressure (in excess of 200...
