Identifying radiated noise problems with Romax Spectrum Acoustic Analysis

Presented by: Dr Michael Platten, Senior Product Manager – NVH & Dynamics

For a thorough understanding of NVH performance in electro-mechanical powertrains, engineers need to be able to simulate both noise and vibration performance. Romax Spectrum Acoustic Analysis adds radiated noise capabilities to the vibration simulation and analysis provided by Romax Spectrum to give you the complete picture.

Based on renowned and trusted meshing and solver technology from Free Field Technologies, the new Acoustic Analysis product option forms a complete end-to-end process which allows you to predict radiated noise quickly and simply, without any in-depth experience of acoustic simulation. In combination with Romax Spectrum’s vibration prediction and system dynamic analysis tools, you can identify and mitigate the root causes of radiated noise problems in a single software product.

What you will learn:

  • The process for the acoustic analysis of an electro-mechanical powertrain including gear and electrical machine noise
  • How to interpret acoustic results and identify root causes to support design change decision-making
