Vibration Localization of a Mistuned Rotating Multi-packet Blade System
These periodic structures are comprised of several blades which are attached to a disk and grouped in packets by shrouds.Since the disk and the shroud possess flexibilities, they create stiffness coupling effects between blades.Because there always exists discrepancy among blades due to manufacturing tolerance, operation wear and environmental change, responses of the mistuned system might be significantly increased compared with the responses of the perfectly tuned system.In this paper, the effects of mistuned blade on vibration localization are investigated.The changes of mode shapes of the mistuned system and transient responses are examined using the proposed model.
