Numerical simulation of magnetic noise and vibrations

Eomys-doc08

This part discusses the different ways to include the assessment of magnetic noise and vibrations in a virtual prototyping workflow of e-machines in terms of accuracy, speed and robustness. Different modelling approaches are reviewed, and numerical challenges of CAE-based calculations are discussed. Algorithms to speed up calculations like vibration synthesis and load extrapolation are presented.
