摘要： In a nondestructive ultrasonic testing method for an implementation in a testing device, defects are installed in a testing area of a structural part by determining reflections on inhomogeneities in a testing area of the structural part. At least one ultrasonic transmitter is provided for coupling ultrasonic excitations into the structural part, and at least two ultrasonic receivers are installed for receiving structure responses to the excitations coupled into the structure. A number of testing points are determined and for each testing point and each location of the ultrasonic receivers, expectancy range data are determined and stored for signal forms being implemented in the testing device. When, an inhomogeneity is present in the respective testing point, excitations are reflected thereon and are measured by the respective ultrasonic receiver. The received reflection data are compared with the stored expectancy ranges to determine the location of a defect.

摘要： The invention concerns nondestructive ultrasonic test equipment for detection and visualization of damage to and in structural components through reflections of introduced ultrasound waves at inhomogeneities in the test area, consisting of primarily piezo sensors, which, depending on how they are driven, can function as transmitter or as receiver for ultrasound waves, and which are permanently attached, for example by gluing, to the damage-critical areas of structural components to be tested and/or monitored, and also of a control device, which is connected to the relevant sensor by electrically conducting wires, so that the received reflected ultrasound waves can be used as imaging data in a suitable device (analysis unit), in order to finally be compared with expected ultrasound images to evaluate any damage that may have occurred. The essence of the invention consists in that the control unit—for example a digital FPGA (field programmable gate array)—is connected to its associated sensor with almost no separation. Another essential inventive concept is to be seen in that the sensors are designed to be two-dimensional or multidimensional such that they can also be used one-dimensionally as needed.
