摘要：

To date, nearly all analyses of lubricant traction behavior in the Hertzian zone of concentrated contact have been performed,with viscosity correlations which understate the effect of pressure and temperature at high pressures. We present viscometer measurements of lubricant viscosity for pressures to 1.4 GPa and temperatures ro 165 degreesC for various lubricants including automotive transmission fluids, aerospace lubricants, a turbine oil. and a metal working oil. Parameters of a free-volume correlation are provided for use in numerical modeling of traction, film thickness, and roughness interactions in concentrated conduct.
