... of the piezoelectric network for mistuned bladed-disk system under engine order excitation. The bladed-disk test structure with piezoelectric patches is shown in Fig. 17 . This system is designed according to the coupled-bladed-disk model presented in Sec. 4 . Base line bladed-disk model system...

... the mistuning issue via mechanical tailoring. Few have focused on developing effective vibration control methods for such systems. This study extends the piezoelectric network concept, which has been utilized for mode delocalization in periodic structures, to the control of mistuned bladed disks under engine...
