Engineer's Guide to Modern NVH Simulation

Diagnosing, coupling, and optimizing noise and vibration in the EV era.

EV powertrains strip away the engine noise that masked everything else, lightweighting trades away stiffness, and pass-by limits keep tightening. The targets move while the models get bigger.

This practical guide walks through how modern NVH simulation keeps up:

• Faster diagnostics with participation factors and PEAKOUT
• Coupled acoustics and trim, interior to poroelastic materials
• Virtual SEA for the high-frequency range
• Substructuring with FRF-based Assembly, no full-vehicle re-solve
• Where machine learning takes design exploration next
