PROJECT TOPICConstruction, Infrastructure & Maintenance
Rail Track Ultrasonic Inspection Trolley
A transportation infrastructure safety concept studying wheel-probe ultrasonic transducers, couplant fluid delivery systems, and real-time B-scan defect visualization to identify internal metal fatigue along railway tracks.
Railway Infrastructure Defect Prevention
- ✓Detects hidden internal steel fissures before they propagate to the rail surface.
- ✓Features lightweight composite construction, allowing two operators to lift it off tracks for approaching trains.
- ✓Correlates GPS and wheel encoder coordinates to pinpoint defect locations within centimeters.
The Engineering Challenge
Problem / Objective
Undetected internal micro-fractures in railway steel rails cause catastrophic rail breaks and train derailments.
