Benefits
Full vehicle NVH represents the most sophisticated form of NVH analysis, with many important benefits.
Simulation of real-world events:
- Loadcases directly simulate customer usage experience
- Problems related to specific loadcase/response are identified
- Clear understanding of cost and benefit
- Can be used to drive physical prototype development
Physical root cause understanding:
- Clearly identified source-path-receiver
- Most effective solutions often come from source reduction
- Understanding of noise/vibration energy transfer paths
- Most sensitive parts and cost effective solutions can be identified
- CAE model can be validated through trend prediction
- Force distribution for subsystem level analysis and optimization can be generated
Ability to apply the entire NVH tool set:
- Effective problem resolution requires using the right tools
- Low frequency – modal alignment and contribution analysis
- Mid frequency – transfer path, point mobility and panel analysis
- Effective isolation
- Mass damper and tuned mass dampers
- Mastic or beads on panels
- Optimization
