Noise, Vibration & Harshness – NVH for Electric Motors
FEA & CFD Based Simulation Design Analysis Virtual prototyping MultiObjective Optimization
FEA based Simulation Design for Electromagnetic multiphysics environments has a significant benefits for noise, vibration and harshness (NVH) analysis of electrical machines and transformers. NVH is an important analysis required by manufacturers of motors used in hybrid/electric vehicles, appliances, commercial transformers and other applications where quiet operation is an essential design parameter. Two-way transient magnetostriction coupling enables the magnetostrictive forces to be added to the magnetic forces and coupled to a mechanical design to predict acoustic noise.
