Automatische wiederkehrende Ultraschallprüfung der Laufflächen von Hochgeschwindigkeits-Schienenfahrzeugen

Using Electro-Magnetic-Ultrasonic (EMUS)-probes the tread of railway wheels is nondestructively inspected for surface defects. The ultrasonic probe is a part of a multi-sensor-system controlling the automatized inspection-procedure. The inspection is performed while the railway wheels are in motion. The inspection data are preprocessed by a my-computer to a protocol containing relevant information on the condition of the tread. This information can be transferred via an interface to the repair workshops.
