Crack Localization in Operating Rotors Based on Multivariate Higher Order Dynamic Mode Decomposition

Crack Localization in Operating Rotors Based on Multivariate Higher Order Dynamic Mode Decomposition

A novel output-only crack localization method is proposed for operating rotors based on an enhanced higher-order dynamic mode decomposition (HODMD), in which the nonlinear breathing crack-induced super-harmonic characteristic components from multiple vibration measurement points are simultaneously e...
