To improve the friction performance of the friction pair of the hydrostatic thrust bearing, the surface with convex textures is designed at the bottom of the oil cavity. The result shows that the oil cavity with the convex structures can significantly improve the friction characteristics of the hydrostatic thrust bearing. To further study the effect of texture parameters (texture radius, texture spacing and texture quantity) on its performance, the method based on the full factor test is used for single objective optimization, and the methods based on the BBD response surface and the NSGA-II algorithm are used for multiple target collaborative optimization. The full factor test with the main effect shows that the best combination with the bearing capacity is 0.5 mm, 7 mm, 7 and 4.91%, and the best combination with the rigidity is 0.3 mm, 5 mm, 5 and 3.61%. The influence of textures on the maximum temperature of oil film is basically unchanged and the bearing capacity is inversely proportional to the friction factor. When considering the interaction between texture parameters, the BBD response surface method is used for multi-objective optimization. The result shows that when the texture radius is 0.7 mm, the texture spacing is 7 mm, the quantity of textures is 6.2, and the area ratio is 8.73%, the optimal response values can be obtained, which the bearing capacity is 8519.31 N and the rigidity is 1.31868 E+12 N/m. The multi-objective optimization analysis of the NSGA-II algorithm based on the BBD response surface model shows that the algorithm can obtain a Pareto solution set. Each set of solutions obtained by the NSGA-II algorithm is the optimal solution. Both the BBD response surface method and the NSGA-II algorithm can be used to solve multi-objective problems.

“…They reported higher consistency between the simulation and experimental results than when the viscosity is assumed constant. Yu et al [180] established a temperature rise equation based on heat transfer paths, which well replicated the experimental results. Their method is valuable for identifying heat points and investigating the heat transfer of large-scale hydrostatic bearings.…”

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.

“…Yu XD established a three-dimensional simulation model of oil film and friction pair of hydrostatic thrust bearing under high-speed and heavy-load conditions and analyzed the oil film pressure field, temperature field, deformation field of bearing friction pair, and oil film thickness field. The results show that the load causes the turntable and base to undergo inward elastic deformation, and the temperature causes the turntable and base to undergo outward thermal deformation [25][26][27][28].…”

The dynamic pressure effect of the clearance oil film of stepped hydrostatic thrust bearing is studied by taking the double rectangular cavity oil cushion as an example. According to the hydrodynamics theory, the average dynamic pressure of lubricating oil film in different clearance height regions is theoretically deduced and calculated, and the dynamic pressure effect of the clearance oil film in the stepped hydrostatic thrust bearing is studied through the combination of theoretical calculation, simulation, and experimental verification. It is found that the theoretical value of the average dynamic pressure of the clearance oil film and the rotational speed show a linear growth relationship with a slope of 275.2. The simulated value of the average dynamic pressure and the rotational speed follow the growth law of the Fourier 1 model. The experimental value of the average dynamic pressure is between the theoretical value and the simulated value, which is basically not affected by the load. In the speed range of 0r/min-200r/min, compared with the viscosity of lubricating oil, the speed is the main factor affecting the dynamic pressure of the oil film of the stepped hydrostatic thrust bearing. The dynamic pressure value of the clearance oil film increases in a stepped fashion along the radial direction of the double rectangular cavity oil cushion. The dynamic pressure value has an obvious upward trend at the junction of the circumferential right oil cavity and the sealing edge and then decreases to 0 after reaching the peak value.
