摘要：

Oil film cavitation can’t be avoided during normal operation of squeeze film damper (SFD). In order to study the change of rotor fundamental frequency vibration during long-term operation of SFD and the erosion of SFD oil film cavitation effect on the metal surface of inner and outer rings of SFD, experimental study of SFD cavitation effect under low oil supply pressure (0.02—0.05 MPa) was carried out based on a full-scale aeroengine high-pressure rotor test rig to investigate the change of rotor fundamental frequency vibration during long-term operation of SFD at critical speed, and the effect of oil film cavitation on the internal and external surface morphology of SFD after long-time operation. The experiment results showed that the SFD oil film cavitation could erode the surface of the inner ring of SFD after long-time operation, forming water drop, oval and irregular pit groups, proving that assessing the SFD cavitation effect near the critical speed is a necessary experiment content for the operation safety of SFD under low oil supply pressure. © 2024 Beijing University of Aeronautics and Astronautics (BUAA).
