NVH
Acoustic and vibration comfort have a growing importance in vehicle development due to increasing customer expectations. Especially new powertrain concepts including electric drives cause NVH challenges. Multi-body and finite element methods are applied as essential part during the vehicle development process.
Powertrain Components
- Structure and air borne noise of eDrive system, engine-transmission unit and gearbox
- Gear whine analysis
- Rattling behavior of gear pairs
- Crank train dynamics
Powertrain Integration
- Definition of non-linear mount characteristics
- Engine start-stop vibration improvement
- Development of customized models for e.g. hydro mounts
- Analysis of interaction with vehicle structure
Car Body and Cabin
- Dynamic stiffness at interfaces
