e-NVH prediction in early electromagnetic and vibroacoustic design phase of electrical machines using MANATEE software (1/8)

e-NVH e-NVH technical webinar 1/8
Objective e-NVH prediction in early electromagnetic and vibroacoustic design phase of electrical machines using MANATEE software
Date 14th April 2020
Hour 9:30 GMT and 16:00 GMT

Organization

The webinar includes:
- A theoretical part of 30 mn on e-NVH
- An application with MANATEE software over 20 mn
- An open question part over 10 mn

Description

Theorical part

- Magnetic force harmonics in electrical machines - notion of wavenumber and frequency
- Phenomenon of resonance between magnetic excitation and structural modes
- Fast electromagnetic modeling techniques such as PMMF and SDM
- Fast vibroacoustic modeling techniques based on equivalent shells
