摘要: A system for inspecting railroad rail using phased array ultrasonic technology measures the time of flight of ultrasonic signals at locations across the rail head to determine the wear profile of the rail. The rail wear profile is then used to adjust the focal laws of the phased array ultrasonic probes to dynamically compensate for changes in the rail profile as the inspection vehicle moves along the rails.

摘要: A system for inspecting railroad rail using phased array ultrasonic technology includes both high-speed and high-resolution inspection modes that obviate the need for an operator to dismount the truck to perform detail inspection. In high-speed inspection mode, the phased array probes operate at fixed angles with respect to the rail to identify potential rail defects as the vehicle moves along the track. The vehicle can then return to the location of a potential rail defect and switch to a high-resolution inspection mode in which the phased array probes sweep over a range of beam angles at the location of a potential rail defect.
