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 |
• | Mass damper and tuned mass dampers |
• | Mastic or beads on panels |
