Simulation of Severe Shear Conditions in Lubrication

The importance of high shear conditions in automotive lubrication is discussed with respect to the influence on lubricant rheological properties. The distribution of shearing effects in lubricated components is also discussed. Two methods of simulating high shear conditions-an elastohydrodynamic lubrication simulator and a capillary viscometer-are presented, along with some data obtained from them on polymer-containing oils.
