Abstract :
The present paper presents a methodology to include noise prediction into virtual prototyping of an electric drive using numerical simulation tools. Field based solutions using FEM and IFEM methods are used in order to simulate electromagnetic induced vibrations and radiated sound in a permanent magnetic motor. The key feature is on the work-flow methodology and the coupling mechanism between the three computational models: electromagnetics, structural dynamics and acoustics. Transient force density signals are integrated over geometric sectors and transformed to frequency domain to be used in the vibration analysis. The complete displacement filed at the machine housing in then used to calculate the radiated sound pressure in the environment and microphone locations.
