  • In order to analyze the static stiffness, structure stiffness and viscous damping of bearing under different factors, the experiment rigs for gas foil bearing (GFB) static and dynamic characteristic experiment were established. By changing the size of the journal of a same bearing, the influences of radial clearance on the static and dynamic properties of experiment bearings were studied. Additionally, the different bump foils, foil materials, ways of heat treatment and other factors affecting bearing elastic structure properties were also investigated. Result shows that, with the decreasing radial clearance of the bearing, the static stiffness and dynamic structure stiffness increase gradually and equivalent viscous damping increases first and then decreases; different bump foils and foil materials play a major role in GFBs' structural properties.
