1 Aerostatic bearing is put forward as bearings for the spindle for its excellent high speed capability.

2 Conventional aerostatic bearings have the problems of vibrations and motion inaccuracy due to the low stiffness.

3 For orifice compensated aerostatic bearings, entrance effect leads differences between actual pressure distributions and traditional laminar flow assumption in gas film of the bearings.

4 Numerical identification aerostatic force is conducted for Sutong Bridge section in CFD modeling.

5 Aerostatic bearing has highly rotating precision and widely applies to the highly precision processing equipment.

6 This paper introduces a design process of a testing stand for aerostatic journal bearings.

7 According to gas lubrication theories,(www.Sentencedict.com) the mathematical model of aerostatic bearing with inherent orifice was developed.

8 In this paper, the boundary element method (BEM) was applied to study static characteristics of aerostatic cylindric bearing.

9 Three active throttle modes also provide variety selection for autonomous control aerostatic bearing.

10 The inherent throttle bearing parameters are optimized according to the maximum stiffness of aerostatic bearing.
