In Situ Raman Microspectrometry of Lubricated Tribologic Contacts. Part Two: Simultaneous Measurements of Pressure, Lubricant Film Thickness and Temperature Distributions in a Running EHD Contact

Résumé

Raman micro-spectrometry is used to acquire point spectra in a running EHL contact. The quantitative method developed in part one of this study, measuring the lubricant film thickness, is complemented by a data treatment yielding quantitative values of the pressure and temperature in the lubricant. The comparison between experimentally measured pressure and film thickness distributions and numerical calculations shows an excellent quantitative agreement. The simultaneous quantitative measurement of pressure, film thickness and temperature distribution carried under pure rolling afforded a direct and quantitative correlation between the three parameters.
