Contact temperatures in rolling/sliding surfaces

This paper studies three related but separate problems concerning the surface temperatures of frictional contacts. The first part considers the surface temperatures of two rolling/sliding contacts when the condition is imposed that there must be no temperature discontinuity over the contact zone, for a range of surface speeds such that V1/V2 varies between + 1 and — 1. The second part studies the surface temperatures when a rectangular heat source moves over the surfaces at various speeds. As the speeds increase the asymptotic expression for the temperature becomes more accurate. The third section considers the way the surface temperatures build up when (a) the contact is repeated, and (b) heat is convected from the free surface.
