Abstract

This three part paper presents the experiment and numerical analysis of the friction of a thin-film rigid disk with circumferential surface texture. In Part III, we examine the friction of a disk on the unworn virgin and worn tracks at various relative humidities. The real contact areas and pressures on both tracks are estimated using the Hertz contact model of two-dimensional asperities in Part I and related to the frictional coefficients on the basis of the meniscus model in Part II. The analysis yields that the effect of meniscus is predominant in the flat contact situation, particularly on the worn track at high humidity, while the effect is negligible in the taper/flat edge contact situation on both the tracks even at high humidity.
