NVH Consulting - Overview
  Consulting    NVH Consulting     Consulting for Vehicle Acoustics     Hybrid-/ Electric Drive Systems
New hybrid-electric drive concepts bring up new challenges regarding noise and vibration comfort:
New disturbing noise sources from electric drive (electric motor, inverter, cooling systems, •)
Disturbance by sudden start and shut down of combustion engine
Unfamiliar or unwanted interior noise / exterior noise (e.g. "whine" noise)
Vibration caused by load changes from electric motor to combustion engine
HEAD consult NVH has data acquisition equipment and analysis tools available that are suitable for successfully working on such tasks.
HEAD consult NVH engineers have contributed to the development of recent hybrid vehicles from the beginning of the prototype phase, and thus have comprehensive experience in this field.
