1) NVH testing on electric machines (benches, vehicle)

• Spectral analysis (FFT, orders, tracking)

• Excitation identification: GMF, slotting, EM harmonics

• Test/simulation correlation

• Noise and vibration diagnostics

• Noise/vibration reduction on prototypes

• Product validation support

• Complex problem-solving

• Test plan implementation

• Technical recommendations

2) Vibration analysis

• Signal processing (FFT, cepstrum, waterfall, order tracking)

• Time and frequency analysis

• Filtering, demodulation, fault detection

• Sensor data exploitation (accelerometers, microphones)
