Response of Bladed Disks With Mistuned Blade-Disk Interfaces [PDF]
Volume 6: Structures and Dynamics, Parts A and B, 2009 This paper focuses on the determination of the effects on the bladed disk forced response of small variations (mistuning) in the blade-disk interface properties as may result from blade seating. A blade-interface-disk mean model is first developed that relies on both the Craig-Bampton approach and a local modeling of the interface. Then, both model and

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 ...
