Fluid lubricated bearings have been widely adopted for supporting components of high-end equipments in the field of metrology, semi-conductor, aviation, strategic defense, ultra-precision manufacturing, medical treatment and power generations. These fields all involve extreme working conditions such as ultra-high moving precision, ultra-high rotation speed, ultra-heavy bearing load, ultra-high environmental temperature, high radiation and high vacuum, which present challenges for the design and optimization of reliable fluid lubricated bearings. Breakthrough of any related bottlenecks will promote the development course of high-end equipments. To further promote the advancement of high-end equipments, this paper reviews the design and optimization of fluid lubricated bearings operated with typical extreme working performances. Targeting on the realization of extreme working perfor mances, the current challenges, the current solutions, the underlying deficiencies and the promising developing directions regarding to the design and optimization of fluid lubricat ed bearings are systematically pointed out. This paper can provide guidance for choosing suitable fluid lubricated bearings and optimizing their structures based on required extremeworking performances.

“…Over the last few years, in the literature, there have been a number of investigations reported on non-Newtonian (shear-thinning and piezoviscous) lubricants, however, they are mainly limited to circular journal bearings. 10–18 Sinhasan and Sah 10 numerically investigated the static as well as the dynamic behavior of hydrostatic journal bearing by using the Finite Element Method. Further, they evaluated the performance characteristics of bearings lubricated with non-Newtonian lubricants using the cubic shear stress law model.…”

The present study investigates the effects of shear-thinning and piezoviscous lubricant on the behavior of inwardly and outwardly spiral grooved hybrid annular thrust pad bearing configurations. The performance of spiral grooved circular and annular hybrid thrust pad bearing configurations with a capillary restrictor is also compared in this study. The influence on fluid film reaction, lubricant flow rate, fluid film stiffness, and damping coefficients have been carried out. The numerically simulated results show that the synergistic effect of spiral grooves and shear-thinning and piezoviscous behavior of the lubricant, have a significant impact on lubrication performance. The maximum percentage difference in the value of fluid film stiffness between outwardly spiral grooved annular recessed hybrid thrust pad bearing with non-Newtonian lubricant and inwardly spiral grooved annular recessed hybrid thrust pad bearing with Newtonian lubricant is found to be 80.6 percent.
