Multiresolution Wavelet Analysis of the Dynamics of a Cracked Rotor
Figure 8
Measured response magnitude of rotor vibrations versus frequency for healthy and notched rotors, without (a) and with (b) external excitation. Rotational frequency is 36.7 Hz, magnetic actuator frequency is 63 Hz, and frequency bands (78.125–156.25 Hz), and (39.06–78.125 Hz), and (19.53–39.06 Hz).
