Fast Structure-Dynamic Simulation of Electrical Machines Using 2D-3D-Coupling

Inhalt:
Structure-dynamic finite-element simulations of electrical machines allow for vibration analysis concerning geometric variants of the regarded motor without prototyping. The huge disadvantage of these types of simulations is their long computing times ever since. In this paper a novel method for the transformation of the surface-force density from the electromagnetic to the mechanical model of the machine is introduced leading to an enormous speed up and more accurate results by far.
