Rapid analysis of low-amplitude sinusoidal roughness in rolling-sliding elastohydrodynamic contacts including thermal effects.

In previous papers, the authors have developed methods for the rapid analysis of low-amplitude roughness in EHL contacts. However, these assumed that the contact was isothermal and ignored the influence of thermal effects in the conjunction. While this is adequate for rolling contacts it leads to errors when rolling-sliding conditions are considered. The aim of this paper is to extend the perturbation analysis to include thermal behaviour. This includes both the temperature rise found under smooth conditions and the cyclic variations in temperature produced by the low amplitude, sinusoidal roughness. [ABSTRACT FROM AUTHOR]
