The authors have previously examined the effect of surface roughness in line and point EHL contacts and have shown that it is the ratio of the wavelength to the inlet pressure sweep that determines the degree of roughness attenuation under the contact. Because of this a single curve can be used to determine the attenuation for all contacts. However this work was carried out for fully flooded contacts and many prac tical contacts operate under conditions of starved lubrication. This paper extends the analysis to this type of conjunction.
