FEA-based simulation in electromagnetic multiphysics environments delivers critical insights for Noise, Vibration & Harshness (NVH) analysis of electrical machines and transformers.
NVH is vital for hybrid/electric-vehicle motors, appliances, transformers and any application demanding quiet operation. Two-way transient magnetostriction coupling integrates magnetostrictive forces into mechanical models to predict acoustic noise.
Results from transient electromagnetic solvers generate force distributions that are mesh-element-accurate. Specialized co-simulation algorithms map these forces directly into mechanical solvers for harmonic and vibro-acoustic analysis.
