Experimental Investigation on a Bladed Disk with Traveling Wave Excitation [PDF]
Sensors, 2021 Bladed disks are key components of turbomachines and their dynamic behavior is strongly conditioned by their small accidental lack of symmetry referred to as blade mistuning. The experimental identification of mistuned disks is complicated due to several

Wavelet Transform-Based Damage Identification in Bladed Disks and Rotating Blades [PDF]
Shock and Vibration, 2018 Blade vibration and blade clearance are effective diagnostic features for the identification of blade damage in rotating machines. Blade tip-timing (BTT) is a noncontact method that is often used to monitor the vibration and clearance of blades in a ...

Operational deflection shape measurements on rotating bladed disks with tracking continuous-scanning LDV [PDF]
Scientific ReportsThe high-speed rotation and complex operational environment of rotating bladed disks make it difficult for traditional contact measurement techniques to achieve effective, non-interfering, and continuous monitoring of their full-field dynamic responses ...
