Temperature at discrete contacts in slipping friction with lubricant

Russian Engineering Research Aims and scope

Abstract

The temperature at individual contacts of rough surfaces, i.e., the flash point T fl in slipping friction with lubricant, is determined numerically. It is shown that the appearance of T fl during thermocycling is a high-frequency wave process. The temperature over the depth of the contacting surfaces is determined, in the form of damping temperature waves. The surface temperature in friction with lubricant may be determined using two parameters: the conventional heating thickness of a uniform body; and the heat-assimilation coefficient.
