... linear motion trajectories and limit cycles. These results suggest that designers should consider using first-half textured surface two-lobe journal bearings operating with ER lubricants to enhance stability and performance under simulated conditions. Originality/value This study presents rotor...

.... Design/methodology/approach To examine the impact of texture preparation on the subsurface characteristics of high-pair interfaces under EHL conditions, a point contact EHL model is developed that takes into account the effect of textured surface topography. The pressure and thickness of the oil film...
