Variable-speed spectrogram analysis


In Manatee software, vibration and acoustic noise of electrical systems induced by e-machine electromagnetic excitations can be efficiently analyzed using spectrogram visualization. The vibration and noise level of each electromagnetic excitation can be analyzed using Order Tracking analysis.


Spectrograms and order tracking analysis are key visualization tools available at the end of every e-NVH simualtion under Manatee. It can be used by mechanical engineers to quickly identify the root cause of resonances in terms of electromagnetic excitation frequency and wavenumber. For more information on how to interpret spectrograms, you can refer to the video below.
