Elastohydrodynamic Lubrication of Elastomeric-Coated Surfaces in Line Contact

Elastohydrodynamic lubrication analysis for an elastomeric layer bonded to an elastic substrate and indented by a rotating elastic cylinder is introduced. The surface elastic deformations are computed from full elasticity analysis of layered elastic half-space. The dry-contact problem was solved first, and the iterative Newton-Raphson method was used to solve the elastohydrodynamic lubrication problem. The lubricant rheological equations were considered in the present analysis. The significant effects of the elastomeric layer thickness on the pressure profiles and film shapes at different operating conditions are presented and discussed.
