Pressure Fluctuations in the Gasostatic Bearing Supply System on Supercritical Operation Mode

Авторы:

This study discusses the oscillatory mode occurring in the gap between the stator and the rotor in gas- static bearing during the outflow of under expanded gas jets out of the supply system, which interacts with the surface of the rotor.

This study discusses the oscillatory mode occurring in the gap between the stator and the rotor in gas- static bearing during the outflow of under expanded gas jets out of the supply system, which interacts with the surface of the rotor. The results of studies on the oscillation regimes, their causes, mechanisms and frequency characteristics of pressure fluctuations in the working fluid supply system and the lubricating layer of gas bearing. A one-dimensional model of central shock oscillations in a gas jet leaking on a perpendicular barrier is considered. Experiments were carried out. The regions, where oscillation regimes exist are revealed.
