| 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. |
