摘要： The invention relates to a method for testing of a train wheel by ultrasound. The method is based on a pulsed ultrasonic field in the train wheel to be tested by an array of individually controllable ultrasonic transmitting transducers acoustically coupled to the train wheel each controlled with a specific analog transient excitation signal. Each analog transient excitation signal generated based on an ultrasonic transmitting transducer-specific stored digital transient excitation function. The resulting echo signals from the train wheel to be tested are recorded by an array of individually controllable ultrasonic receiving transducers. Each ultrasonic receiving transducer can provide an analog, time-resolved echo signal. The received echo signals can be digitized in a transducer-specific way and stored in a set. A plurality of different reception processing rules can then be applied to the latter. Furthermore, the invention relates to a device for carrying out the method.
