Time and angle analysis of Instantaneous Angular Speed signal: impact on average velocity and order spectrums

Résumé

A one-degree-of-freedom rotating system is simulated under different periodic excitations, in order to extract its instantaneous angular speed (IAS) signal. A study of the corresponding spectrums in terms of time- domain and angle-domain frequencies shows a shift in peak locations from one domain to the other. This interrogates the constant speed assumption used for order spectrum analysis, and shows a distinction between angle-averaged and time-averaged velocity.
