Full Vehicle NVH Load Cases
The analysis is to predict the Full Vehicle NVH attributes :
- Idle shake/boom
- Powertrain Noise
- Rough Road Shake/boom
- Coarse Road Noise
- Smooth Road Shake
- Driveline shake/boom
- Axle whine
Subsystem Validation
- Subsystem evaluation and validation
- Subsystem includes Instrument panel, console, HVAC, Seats and to meet NVH targets.
- Finally set the targets for subsystems to get better NVH performance by modal alignment.
Vehicle Integration & Validation
- Model building, working in Vehicle integration and validation till full vehicle level.
- The suggestion of design enablers for improvement of attachment dynamic stiffness to meet the NVH performance targets.
- Comparison and benchmarking of the NVH characteristics of different body structures.
Mode Management
- Mode alignment of Powertrain rigid body, Body, Suspension modes and Tire/wheel modes.
- Modal separation is an important strategy to meet NVH objectives.
- Suggest the Countermeasures to prevent these modes should be separated from front suspension hop and tramp modes and prepare mode alignment chart
