摘要

For a new generation of fluid film journal bearings, the surface texturing approach and smart fluids like ER/MR fluids have been introduced by the bearing designers and lubricant engineers. Thus, the present theoretical investigation related to the combined influence of electro-rheological (ER) fluid lubrication and surface texturing approach on the performance of textured 3-lobe slot-entry hybrid journal bearing has been performed. In this work, Continuous Bingham fluid model has been used to obtaining the apparent viscosity of ER lubricant, consequently derive the modified Reynolds equation. Further, the FEM numerical approach has been used to solving the modified Reynolds equation. The current computed results indicated that the ER fluid lubrication in 3-lobe textured journal bearing improved the values of fluid film stiffness and threshold speed significantly by order of 45.34 % and 23.23% respectively, in respect to Newtonian fluid lubrication in non-textured circular journal bearing.
