Division of frictional heat: The dependence on sliding parameters

Abstract

This paper investigates the dependence of the division of friction - induced heat on the contact parameters through the identification of the behavior of a characteristic function under a combination of loads and speeds. The rubbing pair is assumed to have established contact over a circular spot. Thus allowing the use of pre-existing Green's function for the temperature rise due to an instantaneous disk source. It is shown that the dependence of heat partition on the contact parameters is reflected only at moderate speeds. At high sliding speeds, however, that dependence is merely a function of the coupling between the local thermal properties (thermal conductivity and thermal capacity).
