摘要:Based on modified Carreau constitutive equation, the Reynolds equation was deduced, which considers shear-thinning non-Newtonian property. The flow curve of poly alpha olefin (PAO) 650 was measured with high-pressure rheometer. The rheological parameters were obtained by fitting the related test data. PAO650 elastohydrodynamic lubrication (EHL) film forming properties were studied. Experiment indicates that PAO650 film forming properties based on shear-thinning EHL theory very well agree with the experimental results. The shear-thinning non-Newtonian rheological effect makes PAO650 film-thinning severely. For PAO650, the entrainment rate index of classic EHL film thickness formula needs to be adjusted. The slide-roll ratio has little impact on PAO650 film-forming properties.
