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

• Siemens LMS Test.Lab
• HEAD acoustics
• MATLAB

Process Integration

• PTE-002: Electric Drive Unit Development
• VDC-001: Suspension System Development
• TVL-001: Vehicle-Level Validation Testing
