Textured thrust bearings are capable of providing higher load capacity and lower friction
torque compared to nontextured bearings. However, most previous optimization efforts for
texturing geometry were focused on rectangular dimples and employed Reynolds equation.
Limited studies have been done to investigate the effects of partially textured thrust bearings
with elliptical dimples. This study proposes a new optimization approach to find the optimal
partially texture geometry with elliptical dimples, which maximize the loading capacity and …

Surface texturing has been used to enhance contact performance for decades since 1960s.
Surface structures can tremendously change the friction coefficient of the contact surface.
These structures have been widely used in bearings and seals. According to previous
studies, textured thrust bearings provide more loading capacity than non-textured bearings.
Compared to tapered and step bearings, the dimples can also reduce the friction torque.
