Abstract: Manufacturing tolerances and engine wear produce slight variations in the nominally identical blades of a bladed disk, or blisk. In theory, the vibrational energy of a tuned blisk is evenly distributed among the identical ...

Abstract: Component miniaturization and reduced power requirements in sensors have enabled growth in the field of lowpower ambient vibration energy harvesting. This work aims to increase bandwidth and power output beyond current ...

Abstract: Resonance frequency detuning (RFD) reduces vibration of systems subjected to frequency sweep excitation by altering the structural stiffness state as the excitation frequency passes through resonance. This vibration reduction ...

Abstract: This paper extends the resonance frequency detuning (RFD) vibration reduction approach to cases of turbomachinery blade mistuning. Using a lumped parameter mistuned blade model with included piezoelectric elements, this ...
