摘要

High speed rotors present a lot of stability problems especially when the speed of rotation passes through a critical speed. The non-linear dynamic behaviour of the fluid bearings has, in that case, an important effect. This study presents several models of bearing dynamic behaviour taking into account the flexibility of the shaft: Squeeze film damper (SFD) behaviour is described. This element gives a lot of damping but its behaviour is totally non-linear. The coupling between the axial thrust bearing behaviour and the bending vibrations of the shaft is also studied.
