NVH Analysis for eVTOL & Electro-Motors
Finite Element VTOL, eVTOL & UAM

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.

  • ▶ Transient EM simulation → force vector extraction
  • ▶ Element-based force mapping to structural mesh
  • ▶ Harmonic stress & modal coupling
  • ▶ Optional acoustic analysis for noise prediction

To optimize NVH, our engineers use these force mappings to drive advanced vibro-acoustic simulations. Modal and harmonic stress responses reveal vibration magnitudes and generate waterfall plots for a full acoustic profile.

  • Accurate NVH prediction in eVTOL propulsion systems
  • Design of high-quieting transformers and motors
  • Optimized magnetostrictive coupling models
  • Full-spectrum vibro-acoustic performance maps
