Abstract
- The hydrodynamic lubrication model for multi-layer oil bearings was established based on the Darcy's law. The pores' effects depicted with the Kozeny-Carman equation were considered in the analysis. The effects of the bearing structure and the pore structure on the lubrication properties were simulated and discussed with the finite difference method. Results show that the lubrication properties get worse with the increase of the layer heights and the porosity; a lower-permeability surface will be more beneficial to improve the lubrication performance when the total porosity is fixed. Therefore, in the design of doublelayer oil bearings, the surface porosity should be reduced as far as possible as long as the oil content in pores is guaranteed. This work is referential to the analysis of the tribological properties and the structural design of multi-layer oil bearings. [ABSTRACT FROM AUTHOR]
