    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.

    摘要翻译： 本发明涉及一种借助超声波对火车轮（101）进行无损检测的方法。 该方法基于通过声学耦合到火车轮（101）的独立可控超声发射换能器（110）的阵列（102）在训练轮（101）中产生脉冲超声场。 为此目的，超声发射换能器（110）各自用特定模拟瞬态激励信号来控制，每个模拟瞬态激励信号基于超声发射换能器特定的存储数字瞬态激励函数来生成。 优选地，通过独立可控的超声波接收换能器（110）的阵列（102）来记录来自待测试的轮系（101）的结果回波信号。 每个超声波接收换能器（110）都能够提供模拟的时间分辨回波信号。 接收到的模拟时间分辨回波信号可以以换能器专用的方式数字化，并以回波信号集的形式临时存储。 然后可以将多个不同的接收处理规则应用于后者。 此外，本发明涉及一种用于执行该方法的设备。

    摘要： The invention relates to a push chain (20). This chain has: a plurality chain links (22) situated one behind another along a longitudinal axis x-x of the push chain (20), which each have two side plates (24) that are situated on opposite sides from each other and oriented parallel to each other and that are connected to each other by a connecting plate (26); the side plates (24) and the connecting plate (26) together form an approximate U-shape in cross-section and an elastically deformable backing belt (30), which is attached to the connecting plates (26) of the chain links (22), wherein with an approximately straight alignment of the push chain (20), the chain links (22) rest against one another with contact surfaces (32).
