摘要： The present invention refers to an equipment that allows the performance of fatigue testing at ultrasonic frequencies in a multiaxial loading, more specifically biaxial. The equipment is formed by two components, the horn (1) and the specimen (5), which are coupled with each other. The horn (1) and the specimen (5) possess such geometry that their resonant frequency which, is relevant for the testing, is synchronized with the excitation frequency of the exciter, so that the whole equipment vibrates in free regime. Through its vibration mode, the horn (1) transforms the pure axial cyclic movement which it receives from the exciter into a mixed movement comprised of axial and torsional cyclic and in-phase movements. The specimen (5) possesses, synchronized at the same frequency, its first axial vibration mode and its third torsional vibration mode.

摘要： An apparatus and method detect damage of a component (110) of a system. The damage detection apparatus includes a first grid of sensors (120) arranged in a first orientation on a surface of the component (110) and configured to generate a first set of signals. The apparatus also includes a second grid of sensors (130), independent from the first grid of sensors (120), arranged in a second orientation on an insulating layer (127) on the surface of the component (110) and configured to generate a second set of signals, the second orientation overlapping with the first orientation. A processor (140) detects the damage based on a change in at least one signal of the first set of signals or the second set of signals.

摘要： According to an embodiment, a structure evaluation system includes a plurality of AE sensors, a signal processor, a position locator, a velocity calculator, and an evaluator. The AE sensors detect an elastic wave generated from a structure. The signal processor extracts an AE signal including information on the elastic wave by performing signal processing on the elastic wave detected by the AE sensor. The position locator derives a wave source distribution indicating a distribution of sources of the elastic waves generated in the structure on the basis of the AE signals. The velocity calculator derives a propagation velocity of the elastic wave generated in the structure on the basis of the AE signal. The evaluator evaluates the soundness of the structure on the basis of the wave source distributions and the propagation velocity of the elastic waves.

摘要： A piezoelectric sensor assembly for measuring a force quantity on a structure includes at least one piezoelectric sensor, each including an element and two electrodes each projecting outward from the element. An electronic processor of the assembly is configured to receive data from the sensor, wherein the data includes a voltage with a magnitude that is indicative of a dynamic load (i.e., amplitude modulation mode) placed upon the structure. The processor may be configured to interrogate the piezoelectric sensor for its resonant frequency change which is indicative of the load applied to the structure at low operation frequency and to which the piezoelectric sensor would not otherwise respond well. The dual mode operation of the piezoelectric sensor extends the frequency range of the strain measurement from the dynamic range to static or quasi-static range.
