Vibro-acoustic diagnosis tools


Contrary to general purpose multiphysic simulation software, Manatee comes with a complete set of diagnosis tools to quickly understand the root cause of electromagnetic noise and vibrations in an electrical system.


Besides insightful visualizations such as noise and vibration spectrograms, Manatee provides root cause analysis tools adapted to each engineering discipline involved in electrical system development. As an example they include:

  • Maxwell stress harmonic analysis e.g. using quick Campbell diagram, and magnetic load case contribution to noise and vibration for electrical engineers
  • unit magnetic modal force matrix, and structure mode contribution for mechanical engineers
  • order analysis and transfer path analysis (separation of structure-borne and air-borne noise) for acoustic engineers
