    摘要: A system includes a magnetostrictive strip configured to be wrapped at least partially around an outer surface of a structure. A plurality of coil circuits are disposed on at least one flexible PCB that is configured to be disposed adjacent to the magnetostrictive strip. Each coil circuit is individually controllable by a plurality of channels to at least one of excite or detect guided waves in the structure. A plurality of magnets are configured to induce a magnetic field in the magnetostrictive strip. A connector is configured electrically connect at least one of the plurality of coil circuits and at least one the plurality of channels. A body constructed from a flexible material is sized and configured to at least partially encapsulate at least one other component of the system.

    摘要: A method for performing tomography on a structure supporting modes of guided propagation of elastic waves, the method includes the steps of: acquiring a plurality of signals propagating through the structure by means of a plurality of pairs of non-collocated elastic-wave sensors; for each pair of sensors, i. selecting one mode of guided propagation, ii. converting the measured signal into wave field for the selected mode, iii. determining an anisotropic calibration coefficient on the basis of a wave-field propagation model evaluated depending on the anisotropic wavenumber and on the distance between the sensors of the pair, and on the basis of the wave field or of a reference wave field corresponding to a healthy state of the structure, calibrating the wave fields using the determined calibration coefficients, performing tomography on the structure on the basis of the calibrated wave fields.

    摘要: A method for calibrating an ultrasonic sensor includes: transmitting a first ultrasonic signal from the ultrasonic sensor toward a first surface of a contact device when a model is on the first surface of the contact device; generating ultrasonic images by sampling a first ultrasonic echo signal, the first ultrasonic echo signal comprising a reflected signal of the first ultrasonic signal, at a plurality of reception time points; detecting portions of the ultrasonic images, wherein detected portions of the ultrasonic images are most similar to corresponding portions of a reference image of the model compared to other portions of the ultrasonic images having same positions as the detected portions and detected at different reception time points of the plurality of reception time points than the detected portions; and storing the reception time points corresponding to the detected portions of the ultrasonic images.

    摘要: An ultrasonic inspection system includes an ultrasonic probe and an analyzer. The probe includes a flexible delay line and an ultrasonic transducer array at a first delay line end. A second delay line end can contact a target. The analyzer can receive ultrasonic echoes from the ultrasonic transducers representing amplitude of ultrasonic signals reflected from the target as a function of time from transmission. The analyzer determines a maximum amplitude of the echoes received by each transducer, scale the maximum amplitudes based upon a greatest maximum amplitude, and bin the scaled maximum amplitudes. The analyzer assigns each bin a color and generate a C-scan based upon the scaled amplitudes. Each C-scan pixel can correspond to at least one transducer, and the relative position of each C-scan pixel can correspond to the relative position of the ultrasonic transducer represented by the pixel. Each pixel can be displayed with its assigned color.

    摘要: The present disclosure provides a system and method for real-time visualization of a material during ultrasonic non-destructive testing. The system includes a graphical user interface (GUI) capable of showing a three-dimensional (3-D) image of a composite laminate constructed of a series of two-dimensional (2-D) cross sections. The GUI is capable of displaying the 3-D image as each additional 2-D cross section is scanned by an ultrasonic testing apparatus in real time or near real time, including probable defect regions that contain a flaw such as an air pocket, delamination, or foreign object within the composite. Furthermore, in one embodiment, the system includes an artificial intelligence capable of highlighting foreign objects within the 3-D image in real time or near real time and providing data regarding each object area, such as the depth, size, and/or type of each defect.
