Nihon Kikai Gakkai ronbunshu, 2021 Although bladed disks are nominally designed to be cyclically symmetric (tuned system), the vibration characteristics of all the blades on a disk are slightly different due to the manufacturing tolerance, deviations in the material properties, and wear ...

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 ...

Study on optimal design of mistuned bladed disk
Nihon Kikai Gakkai ronbunshu, 2018 Although, in designing blades, it is assumed that all blades on a disk are identical (tuned system), the vibration characteristics of the blade is slightly different due to the manufacturing tolerance, the deviation of the material property, and so on ...

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 ...

Piezoelectric-Based Vibration Energy-Harvesting for Bladed Disks: Modeling and Comparative Performance Analysis of Interface Circuits [PDF]
SensorsFocusing on the self-powering demand of aircraft engine bladed disks (blisks), this paper investigates piezoelectric vibration energy-harvesting modeling and non-linear circuit performance. A multi-sector electromechanical coupled model is established to

A Comparison between Two Reduction Strategies for Shrouded Bladed Disks
Applied Sciences (Switzerland), 2018 Shrouded bladed disks exhibit a nonlinear dynamic behavior due to the contact interfaces at shrouds between neighboring blades. As a result, reduced order models (ROMs) are mandatory to compute the response levels during the design phase for high cycle ...
