Abstract: It is well known that the vibrational behavior of a mistuned bladed disk differs strongly from that of a tuned bladed disk. A large number of publications dealing with the dynamics of mistuned bladed disks are available ...

Abstract: The design of bladed disks with contact interfaces typically requires analyses of the resonant forced response and flutterinduced limit cycle oscillations. The steadystate vibration behavior can efficiently be calculated ...

Abstract: The presence of a crack in a blade can change the natural frequencies of that blade. It has long been a goal to detect blade cracks by assessing the change in a measured vibration frequency of the blade over time. It has ...
