STUDY ON STATIC AND DYNAMIC CHARACTERISTICS OF A GAS-LUBRICATED JOURNAL BEARING WITH ACTIVE CONTROLLED RESTRICTOR

Abstract

Abstract: Combining surface-restriction with active controlled restriction, a new gas-lubricated journal bearing with active controlled restrictor is proposed. Combining engineering calculation method with finite element method (FEM), the general principle and bearing configuration are explained, and the theoretical model of the bearing is given. The problem that it has to alternate much time and convergence progress is very slow in computing is better solved. Both theoretical and experimental results confirmed the good characteristics of the bearing through the active feed-back controlling of bearing working pressure by the active controlled restrictor.

Key words: Active controlled restrictor, Dynamic characteristics, FEM, Gas-lubricated bearing, Static characteristics
