NVH Analysis Skill
Purpose
Provide noise, vibration, and harshness analysis and optimization expertise for vehicle refinement and sound quality engineering.
Capabilities
- Modal analysis and transfer path analysis
- Order tracking and Campbell diagrams
- Source-path-receiver analysis
- Panel contribution analysis
- Acoustic simulation (SEA, BEM, FEM)
- Sound quality metrics
- EV/HEV-specific NVH (inverter whine, motor noise)
- Pass-by noise simulation
Usage Guidelines
- Identify NVH sources through transfer path analysis
- Use order tracking for rotating component analysis
- Apply acoustic simulation for early design guidance
- Evaluate sound quality for brand character
- Address EV-specific noise sources
- Validate against pass-by noise regulations
Dependencies
