Identification of Mistuning Based on Forced Response Measurements and Assessment for a Real Compressor Blisk

We develop a novel method for the identification of mistuned blisks. The method relies on forced response measurements in a certain target frequency band. Modal stiffness deviations and an overall structural damping coefficient are obtained using a least-squares fit, fully consistent with a componen...
