Comprehensive Vibration Study for a High-Precision Manufacturing Facility

Project Overview:
Darren led a comprehensive vibration study for a high-precision manufacturing facility experiencing unexplained performance issues. Using sensors, a laptop, a DAQ card, and FFT spectrum analysis software, he identified and resolved critical vibration sources that were affecting both facility infrastructure and equipment operation.

Scope of Work:

  1. Problem Identification:
    The facility’s engineers reported inconsistent performance in key production equipment and a higher-than-normal defect rate during metrology checks.
  2. Field Survey:
    Darren performed an on-site vibration survey using precision sensors placed across critical locations (machinery bases, foundation points, and surrounding infrastructure).

    • Tools Used:
      • FFT spectrum analysis software for frequency diagnostics.
      • DAQ (Data Acquisition) card for accurate, real-time data capture.
      • Portable setup with a laptop and sensors to enable rapid deployment.
  3. Data Analysis:
    Using FFT analysis, Darren isolated several vibration sources:

    • Harmonic vibrations caused by nearby HVAC systems.
    • Ground vibrations transmitted from truck traffic outside the facility.
    • Minor resonances from improperly mounted equipment.
  4. Recommendations & Implementation:
    • Suggested passive isolation platforms for metrology tools to improve measurement consistency.
    • Recommended adjustments to equipment mounting to eliminate internal resonance.
    • Collaborated with the facility’s engineering team to reschedule heavy truck operations during off-peak hours.
  5. Outcome:
    • Defect rates during metrology checks reduced by 30%.
    • Production output increased by 10% due to fewer operational disruptions.
    • The vibration study provided the foundation for long-term improvements in facility layout and machine maintenance schedules.
