摘要： Various approaches for assessing a part for a defect are disclosed and that are based upon SAW modes. In one embodiment, a part-under-test (120) is excited. One or more SAW modes (206) are identified in the frequency response (240/260) of the part-under-test (120). A SAW mode area (248/266) in the frequency response of the part-under-test (120) is compared with a baseline SAW mode area (238/258) of a baseline frequency response (230/250) (and which may be associated with an acceptable part). This comparison may be used to determine if the part-under-test (120) may be characterized defective in at least some respect.

摘要： The damage length measurement system has an object being measured that comprises a plurality of members is vibrated by an oscillator, and the vibration that propagates through the object being measured is detected by three sensors. A measurement apparatus analyzes that vibration wave, and measures the arrival time of the maximum peak. Using the fact that the time for a wave to propagate between two vibration detection sensors separated by a set interval is fixed, the measurement apparatus determines whether the difference in arrival time between two sensors is within a set reference range that includes the vibration propagation time between two vibration sensors. When the measurement apparatus determines that the difference is not within the set reference range, uses the fact that that wave is delayed compared to the wave that was to be detected.

摘要： A technique for utilizing tube waves to measure sound speed of fluids and other properties in the frequency range of about 5 to 100 kHz. A drill string is equipped with a sensor tube having a cavity filled with a downhole fluid such as borehole mud or formation fluid. An acoustic transmitter and an array of acoustic receivers are mounted on the tube in direct contact with the fluid. Processing circuitry calculates a property, e.g., sound speed, of the fluid based on time-of-flight of an acoustic signal generated by the transmitter and received by the array of receivers. Alternatively change in signal phase as a function of frequency may be employed by the processing circuitry. The technique is particularly suited to measuring the sound speed of borehole mud in situ.

摘要： The present invention relates to a structural health monitoring system, for example a system used in the non-destructive evaluation of an aircraft structure. The present invention provides a method and apparatus for evaluating one or more anomalies within a structure using a structural health monitoring system that includes at least three transducers arranged in operative contact with the structure such that no two transducers are aligned to be parallel. A transducer excites an elastic wave that propagates through the structure, and reflections from any anomalies within the structure are collected by the three transducers. These collected signals are analysed to identify an anomaly within the structure. Time of flight techniques are used to determine the location of the anomaly.

摘要： A method of predicting workpiece deformation prior to machining that causes the workpiece to deform through release of residual stresses. The method includes emitting a beam of ultrasound waves onto the workpiece surface in such a way that a longitudinal wave is propagated in a given direction under and substantially parallel to the surface, positioning at least one transducer in receive mode on the surface to receive a subsurface longitudinal wave that has been propagated, and measuring the propagation velocity of the subsurface longitudinal wave. The method further includes performing these steps in two workpiece regions, a first region sensitive to residual stresses and a second region somewhat insensitive to residual stresses, then calculating a difference in propagation velocity between the velocity measured in the first region and the velocity measured in the second region and from the difference, deducing the deformation that will result from machining the first region.

摘要： A method for determining components of a tube casing surrounding a tube uses amplitude measurements of an acoustic signal wavefront emitted inside the tube. The acoustic signal wavefront is affected by the components of the tube casing while propagating in the tube. Various parameters such as an attenuation A(E) of the amplitude inside the tube and a coupling amplitude Eo may be determined. Theses parameters may be inserted in equations that are inverted to obtain a percentage of cement bonded φC in the tube casing, a percentage of cement de-bonded φD in the tube casing and a percentage of liquid φW in the tube casing.
