1. 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
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
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
