2021, Journal of Sound and VibrationCitation Excerpt :The effects of cracks and rotational speed on the natural frequencies were shown by some numerical calculations. Kuang et al. [15] studied the effect of crack depth and rotational speed on the localization phenomenon in a rotating blade-disk system and results were verified by numerical simulation. However, the effects of crack size and rotational speed on the natural frequencies of blades are concerned independently in Kuang's work.
Investigation on the parameter sensitivity of bladed assemblies undergoing mistuning features
2021, Applied AcousticsCitation Excerpt :Castanier [7] gave a review on reduced-order modeling techniques for the simulation and analysis of blade vibration of gas-turbine engines and emphasized crucial developments that have enabled better prediction and understanding of the forced response of mistuned bladed disks. Some studies focused on the mode localization phenomenon due to the mistuned blade [8–11]. In the recent past, the focus has shifted to specific mistuning due to blade length.

2015, Mechanical Systems and Signal ProcessingCitation Excerpt :The conclusions obtained from these structures may not be suitable to centrifugal impellers. Regarding axial compressors, several investigations [20–25] have been conducted on the vibration response of bladed disks with a single crack using simplified or finite element-based models. Kuang et al. [20] simplified blades as Euler–Bernoulli beams and treated the crack as local disorder of the system to study the effects of local disorder on the mode localization.
