... 30.24 ISOLATION OF RANDOM VIBRATION In random vibration, all frequencies exist concurrently, and the amplitude and phase relations are distributed in a random manner. A trace of random vibration is ... described as narrow-band random vibration or a random sine wave. The characteristics of random vibration are defined by a frequency spectrum of power spectral density (see Chaps. 1...
