| description | This paper introduces the grease average flow model considering non-Newtonian characteristics into the grease-mixed elastohydrodynamic lubrication (EHL) numerical analysis. On this basis, a method of grease EHL analysis is established with the roughness coupled indirectly. The effect of the rheological parameter on the variety law of the lubrication state is studied. The results show that the rheological parameter affects the lubrication state versus the dimensionless speed, material, and roughness. Finally, the film thickness and asperity load prediction formulas are derived based on the numerical simulation results, which are suitable for various greases obeying the Ostwald model. |
