Calculation of the Boundaries of the Region of Stable Equilibrium of a Rotor in Pressurized Gas Bearings,

Abstract

A study is reported of the stability of the equilibrium state of a rotor in a pressurized gas bearing. The equations for the perturbed motion of the rotor are considered together with the Reynolds equations for the pressures in the lubricant layer. The conditions of equilibrium stability are established by the small perturbation method in a linear approximation. A numerical method of solving the basic equations is outlined, and the results of certain computer calculations are presented.
