Fatigue analysis is one application for which PSD analysis is useful.
Use a constant function to ensure that the magnitude of probable load is the same at all frequencies.
The shape of the power-spectral-density input function is dependent upon the probability of loading for each frequency, and the variation in likely load magnitude as a function of its frequency.
