Influence of a sealed Squeeze Film damper on rotor dynamics : experimental analysis
Résumé
The system studied is a dual-shaft rotor on which one is mounted a Squeeze Film Damper (SqF) equipped with two piston ring seals. Feeding pressure effects on the overall dynamics are shown, especially on the response level at critical speeds, their frequency positions and corresponding deformed shapes. Physical phenomena present inside the SqF and explaining the observed effects are analyzed. The use of a suitable feeding pressure for each critical speed crossed over during the run-up is shown.
