Harmonic source analysis

MANATEE offers several possibilities to understand the origin of harmonic magnetic forces by removing a given set of time and space harmonics, running the vibro-acoustic simulation and comparing with the reference case with all time and space harmonics. You may be able to :

This analysis can either be done at fixed speed (on the output Output.Acoustics.LwrA for instance) or at variable speed on the maximum sound power level (Output.Acoustics.LwrA_max).

The choice of some specific harmonics to cancel is done using the harmonic decimation tool. This feature is also particularly useful for teaching purposes.

An automated harmonic analysis is also available to automatically remove the main harmonic sources and check the influence on noise & vibrations.
