- Summary:
- With increasing efforts towards rapid electrification ofpowertrains, NVH engineers face new set of challenges. Eliminationof the IC engines drastically reduces powertrain borne noise levelsbut unmasks other existing noise sources like wind, road, ancillarydevices and squeak and rattle. In addition, the new tonal soundsfrom electro-mechanical drive systems makes the noise more annoyingeven though it is lesser quantitatively. In summary, theelectrification of powertrains has shifted powertrain NVHdevelopment from overall level to sound quality with differenttargets requiring several electro-mechanical solutions withinnovative simulation, testing, and optimization approaches. Thepurpose of this paper is to present a novel diagnostic approach todetect, quantify and optimize the prominent sources of electricmotor borne noise and vibrations considering the multi-physicsinteraction between electric motor structural mechanical propertiesand electromagnetic phenomena. The Maxwell electromagneticexcitations are computed and applied on the stator structural meshto compute the radiated noise using vibro-acoustic simulations. Adiagnostic approach is established to investigate the individualand interactive effects of Maxwell forces and structural modalbehaviour of the electric motor on the radiated noisecharacteristics. The interpretation from these diagnostics resultsare used to identify, rank and optimize motor design parameterscontributing in NVH responses in addition to structuralmodifications on the motor radiating surface
