Abstract
High speed rotors set a lot of stability problems especially when the speed of rotation is going through a critical speed. The dynamical behavior of the fluid bearings has, in that case, an important effect. This study presents two examples of coupling between fluid element and flexibility of the shaft:
- The coupling between the axial thrust bearing behavior and the bending vibrations of the shaft will be studied.
- The behavior of a shaft with flexible wheel-shaft and bearing-shaft coupling.
