Abstract

The purpose of this paper is to present some experimental results on the transient response dynamics of a rotor system with flexible damped support due to the event of simulated blade loss. Experiments under different sudden unbalances applied on the rotor system with various SFD film clearances at different rotational speeds were performed. The instability conditions characterized by limiting circle orbits for large amplitude at damper location were determined and some special phenomena such as lock up, bistable jump and subharmonic etc. have been observed. The effectiveness and the capability of SFD for suppressing instability are analyzed.
