2016 Maintenance Innovation Challenge
Easy to Use Portable Vibration Data Logger
PROBLEM STATEMENT
• Vibration characterization of all mechanical systems is
needed to provide:
•
Environmental specifications to enable design of
new technology and systems for our military
•
Operational data for engineers to determine how,
why, and when components fail
•
Qualify new systems
• Currently a significant labor and material investment is
needed to outfit aircraft with required equipment and
instrumentation
•
Costs approach $100K per test flight
• Limited number of outfitted aircraft results in long lead times
for engineers
TECHNOLOGY SOLUTION
• Developed in a Navy RIF BAA program
• Handheld unit embedded with:
• Two triaxial accelerometers (one for high frequency
shock and vibration, another for lower frequency)
• Temperature and pressure sensors
• CPU for data processing, triggering recordings, and
time stamping
• Analog filters
• Battery for power in remote locations
• >2GB of memory for large recordings
• Easy to use and free software for data processing and
analysis
BENEFITS
• Cost effective
•
Ranges from $1,000 to $2,500 per unit
• Wide measurement range
•
±25g, 100g, 500g, and 2,000g options
• Time stamped data to correlate vibrations to known events
• High sample rate (20,000 Hz per channel)
• Long rechargeable battery life (>12 hours)
• Lightweight (40 grams for plastic, 65 for aluminum enclosure)
• Shock, vibration, and EMI qualified
• Over 4 billion data points of onboard memory
• Micro-USB for set-up and download
• Expected NAVAIR savings of $3-5M in four years
• Commercially available
