摘要： The present invention relates to a method for making a device for monitoring the structural integrity of structures such as beams, plates and shells, made of isotropic, anisotropic and/or laminated material, and to such a device. The method provides to define a asymmetric directivity function D(k1,k2) that has, in the domain of wave numbers, a plurality of maxima arranged on different concentric circumferences having center in the origin of the axes. Then a load distribution in spatial coordinates f(x1,x2) is computed by inverse Fourier transform of the directivity function D(k1,k2). Then therefore the device is made with the electrodes, whose shape is obtained by gathering the values of the load distribution f(x1,x2) in the plane having for coordinates the set of real numbers and imaginary numbers, defining at least two sectors of said plane that comprise at least one real value and one imaginary value.

摘要： An ultrasound test apparatus for polymeric materials (e.g., plastic pipes) includes a low-absorption housing that at least partially encloses an ultrasound transducer, wherein the transducer emits a low frequency wide angle ultrasound beam with a narrow bandwidth. In especially preferred configurations and methods, the apparatus will detect flaws in polymeric pipes, and especially in welds or stressed zones of such pipes, wherein defects of less than 4% of the wall thickness (up to 4 inches) are detected. Further disclosed are configurations and methods for nondestructive detection of lack-of-fusion defects in polymeric pipes.

摘要： During a first method for detecting a crack (29A, 29B, 29C) in a railway wheel (1) which can rotate around an axis (5) of rotation, an ultrasonic wave (23, 33) is irradiated into the wheel disc (9) through the running surface (13) and through the wheel flange (11). An ultrasound transducer (21, 31) provided for this is moved relative to the test piece in an essentially circular manner around the axis (5) of rotation. The irradiation direction of the first ultrasonic wave (23, 33) is slued in the wheel disc plane (25). During a second method, an ultrasonic wave (53) is irradiated into the wheel hub (7) though a face of the wheel disc (9), and the irradiation direction of the first ultrasonic wave (53) is slued. An ultrasound transducer (51) provided for irradiating the first ultrasonic wave (53) is moved relative to the railway wheel (1) in an essentially circular manner around the axis (5) of rotation. In addition, the invention provides devices for carrying out the methods which comprise one-dimensional or multidimensional group irradiators (21, 31, 51, 61, 71, 81).

摘要： The invention relates to a method for detecting a defect (29) in a railroad wheel (3) of a railroad train (1). According to the inventive method, the railroad train (1) is moved at a predetermined traveling velocity (V). A first ultrasonic probe (31) mounted on a inspection car (11) in a moveable manner is acoustically coupled, preferably to the running surface (19) of the railroad wheel (3). The inspection car (11) is also moved in a direction of travel at said traveling velocity (V). Additional, ultrasonic probes (33, 35, 37) which are arranged in an offset and/or oblique manner can be provided. The directions of emission of the ultrasonic probes (31, 33, 35, 37) are preferably panned in a tangential plane (51) by a component. The invention also relates to a corresponding device for carrying out the inventive method.

摘要： The invention relates to a method for measuring physical or technical values of liquids by means of an acoustic transmission system for Rayleigh waves according to a wave guide principle. The inventive device comprises at least one measured section (100-106) formed by a solid surface made of nonpiezo-electric material. Said measured section can be brought into contact with the medium to be measured or with a transmission system, wherein at least one part of the acoustic wave emanating from the transmitter (1, 1') passes through at least one mode converter (3, 4, 34, 34', 34'', 34''', 34'''') on its way to the receiver (2, 2') and this part of the wave energy mode is converted at least partially by a Rayleigh wave (RW) into a volumetric sound wave (VW) or vice-versa. The device has a measured section made from a nonpiezo-electric material and the elements for exciting Rayleigh waves and/or for sensing Rayleigh waves and the measured section form separate components. When the principle of mode conversion is applied, at least one mode converter (3, 4, 34, 34', 34'', 34''', 34'''') is arranged, interacting with the measured section (5') or with an area connected to said measured section (5'). Said converter converts a volumetric sound wave (VW) running from the transmitter (1, 12) to the measured section (5') into a Rayleigh wave (RW) and/or converts a Rayleigh wave (RW) returning from said measured section (5') to the receiver into a volumetric sound wave (VW).
