Dynamic Noise and Vibration Workflow for Electrical Drive Train

With the electrification of power trains, studying the effects from electromagnetism becomes a new challenge for noise and vibration (NV) analysis. This Tech Talk will introduce you the latest NV workflow from SIMULIA, in which controller and inverter effects are taken into consideration in the analysis of NV by using CST(electromagnetic domain), Simpack/Abaqus (structural domain) and Dymola (system domain).    

Highlights:

• Approaches with different fidelity to predict noise and vibration behavior of an electrical drive train
• Integrated workflow among electromagnetic-, structural- and system domain
• Incorporated inverter effects in the noise and vibration prediction
