Abstract: The focus of the paper is the analysis of mistuning, which are small deviations of the blade properties, e.g., due to manufacturing tolerances. The resonant amplitudes of turbine blades are very sensitive to these deviations ...

Abstract: This article discusses the problem of exceeding amplitudes of mistuned structures caused by accelerated traveling waves type excitation, i.e., traveling waves with time variant frequencies. These waves cause resonance ...

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 ...
