Influence of MHD Lubrication and Textured Surface in EHL Line Contact
The present numerical study investigates the combined effect of micro-texture and magneto hydrodynamic lubrication behavior on the performance of elastohydrodynamic lubrication (EHL) line contact. Micro-textures, which are found in the inlet zone of a contacting surface, are studied, and modified Re...

| description | The present numerical study investigates the combined effect of micro-texture and magneto hydrodynamic lubrication behavior on the performance of elastohydrodynamic lubrication (EHL) line contact. Micro-textures, which are found in the inlet zone of a contacting surface, are studied, and modified Reynolds, elasticity, and load balance equations have been solved using Finite element analysis (FEA) and Generalized Minimal Residual Method (GMRES). A parametric study has been performed to optimize the micro-texture shapes in the contacting surfaces for different values of magneto hydrodynamic lubricant parameters. The numerical results show that increasing externally applied magnetic field and micro- texture shapes enhances the values of performance parameter of EHL line contact. Finally, the variation in the steady-state EHL characteristics pertaining to unidirectional pure sliding contacts due to an artificially produced inlet zone of micro-texture shapes (IZMTS) is investigated numerically. The enhancement in central and minimum film thickness is found to be up to 38 and 28% respectively, along with 33.28% reduction in coefficient of friction. |
