Union Pacific Uses New Tech to Harness Steel Vibrations
Omaha, Neb., June 28, 2017
What do rock 'n' roll and bridge inspectors have in common? Just as the strings' vibrations tell a guitarist his instrument is properly tuned, the same kind of vibration or movement can give an engineer insight into a bridge's durability. It's called "smart monitoring." How this technology could revolutionize bridge inspections is detailed in a new Inside Track story published Wednesday on Union Pacific's website.
"Picture a paperclip," said Union Pacific's Director of Bridge Maintenance Todd Martindale. "If you repeatedly bend it, it wears out and breaks. Steel components, depending on where they're located in the bridge, can develop fatigue cracks in a similar manner."
The article highlights three partners working with Union Pacific to develop smart monitoring technology that identifies potential bridge defects: the University of Nebraska-Lincoln, University of Michigan and SENSR Monitoring Technologies.
