Root Cause Studies

Hybrid Approach

We possess a full complement of experimental and analytical tools to understand product noise and vibration issues.  GLSV can assist clients in understanding noise and vibration issues whether the problem is related to high noise or vibration levels effecting operator safety and ability to communicate, vibration levels causing machine malfunction and quality issues, or vibration issues resulting in decreased component life to list a few typical projects.

NVH Root Cause

GLSV is unique in its offering of NVH root cause capabilities due to exceptional experience, outstanding facilities, world class measurement equipment, and remarkable engineering analysis tools.

Structural Root Cause

Capabilities for identifying and mitigation structural failures include:

  • Experimental strain
  • Experimental vibration/acoustic
    • Modal Analysis
    • Operational Deflection Shape
    • Transfer Path Analysis
  • Numerical modeling of static, vibration, and vibro-acoustic problems

Typical failure scenarios include:

  • Static overstress conditions (low cycle)
  • Vibration induced fatigue (high cycle)
  • Acoustic fatigue
