Micro-Vibration Analysis and Optimization of Aerostatic Bearing with Pocketed Orifice-Type Restrictor

Journal of Applied Fluid Mechanics, 2018
For an aerostatic circular thrust bearing with a single pocketed orifice-type restrictor, the flow field in the bearing clearance is analyzed numerically, and the formation mechanism of the bearing micro-vibration is investigated.

The Simulation of Gas Film Flow Field in Aerostatic Thrust Bearing

Sustainable Development Research
Based on the CFD software, the numerical simulation and visualization of the gas flow in the gas film gap are carried out. Considering the influence of gas flow, the laminar flow model was adopted when the clearance is relatively small and a realizable model was adopted for large gaps.

Numerical investigation on dynamic tilt characteristics of aerostatic thrust bearings

Journal of Physics: Conference Series
Abstract Aerostatic bearings are widely used in ultra-precision measurement due to their near-zero friction. However, their inevitable tilt can cause angular error motion, reducing the measurement system’s precision. This study establishes a dynamic model of the bearing’s tilt characteristics using the tilt-perturbed Reynolds equation ...
