(54)IN-MOTION HIGH-SPEED NON-DESTRUCTIVE EVALUATION FOR RAILCAR AXLES


(57) An example system (100) for inspecting railcar axles includes a flash source (106), an infrared camera (108), and a trigger sensor (110). The flash source (106) is configured to apply a thermal pulse toward a surface of a railcar axle (102) of a railcar wheelset (104), while the railcar wheelset (104) is on a track (122). The infrared camera (108) is configured to capture infrared data indicative of a thermal response of the surface of the railcar axle (102) to the thermal pulse. The trigger sensor (110) is configured to trigger the flash source (106) to apply the thermal pulse based on a position of the railcar wheelset (104) on the track (122). The example system can also include a processor (112) configured to determine whether the captured infrared data is indicative of a crack on the surface of the railcar axle (102), and a vision camera (120) configured to capture an image of the surface of the railcar axle (102).
