Cracked axle, resonance shift, automated detection, wayside detector, rolling stock, tests

The Federal Railroad Administration supported the performance of semi static tests on two cracked axles as part of the Resonant Acoustic Wayside Automated Cracked Axle Detection (RAWCAD) project. The performance of detection algorithms for distinguishing frequency shift in cracked axles was evaluated at the Transportation Technology Center (TTC) in Pueblo, CO. Two cracked axles were tested, one on each of the two railcars. The remaining axles on both cars were unblemished. Originally, locations of the cracked axles were unknown to the analyst, making this initial evaluation a blind test of the detection algorithm.
