: A time history tells you what happened. It does not easily tell you the power distribution across frequencies—information critical for understanding resonance and avoiding it.
Spectral methods, on the other hand, offer a promising approach for analyzing vibration fatigue. These methods are based on the representation of random vibrations in the frequency domain, allowing for a more accurate and efficient analysis of fatigue damage. In recent years, spectral methods have gained significant attention in the field of vibration fatigue, and this article aims to provide a comprehensive review of the current state-of-the-art. vibration fatigue by spectral methods pdf better
