High-speed stability of a rigid rotor supported by aerostatic journal bearings with compound restrictors
TL;DR: In this article, the instability of a rigid rotor supported by aerostatic journal bearings with compound restrictors was investigated numerically and experimentally, and it was found that this type of aerostastic bearings showed a much higher threshold speed for instability compared with bearings with inherently compensated restrictors.

The comparison in stability of rotor-aerostatic bearing system compensated by orifices and inherences
TL;DR: In this article, the static and dynamic characteristics of a rigid spindle supported by aerostatic bearings which are compensated by orifices and inherences are studied. And the stability thresholds of both critical inertial force and critical whirl ratio belong to the motion equation of the rigid rotor-aerobearing system which is obtained by perturbation method.

Performance analysis of high-speed spindle aerostatic bearings
TL;DR: In this article, a detailed theoretical analysis of bearing performance is presented, in which the gas flow within the bearing is initially expressed in the form of simplified dimensionless Navier Stokes equations, and the nonlinear dimensionless Reynolds equation is then derived and subsequently discretized using the Newton method.
