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
