Noise, vibration, and harshness analysis and optimization expertise

General

What this skill does


# 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

let-fate-decide

Included

Draws the 12 Houses of the Zodiac Tarot spread to inject entropy into planning when prompts are vague, ambiguous, or casually delegated. Interprets the spread to guide next steps. Use when the user says 'let fate decide', 'YOLO', 'whatever', 'idk', or other nonchalant phrases, makes Yu-Gi-Oh references, or when you are about to arbitrarily pick between multiple reasonable approaches. Prefer over ask-questions-if-underspecified when the user's tone is casual or playful rather than precision-seeking.
