Monitoring rail track bolt loosening using fiber-optic distributed acoustic sensing

Monitoring rail track bolt loosening using fiber-optic distributed acoustic sensing

Bolt loosening in railway tracks poses considerable safety and operational risks, such as track misalignment, wear and tear, maintenance challenges, and operational disruptions. This study explores the use of acoustic signals from wheel-rail interactions to detect bolt loosening. Specifically, it de...
