Operational Modal Analysis of a Rotating Structure Subject to Random Excitation Using a Tracking Continuously Scanning Laser Doppler Vibrometer via an Improved Demodulation Method

L. F. Lyu et al.

Summary: A new operational modal analysis method is introduced, which utilizes a nonuniform rotating beam model, an image processing method, and an improved demodulation method to estimate the modal parameters of a rotating structure subject to random excitation. Experimental investigation confirms the feasibility and accuracy of this method.
