| Abstract: | An unsteady Reynolds equation for Eyring fluid was derived and solved simultaneously with the elastic equation by means of finite difference method. More attention was given to the analysis of non-Newtonian effects on EHD lubrication process. The full numerical solution of the EHD problem with Eyring fluid not only provides more precise pressure distributions and film profiles for traction and fatigue calculations, but also lay a foundation to microelastohydrohynamic lubrication studies. |
