    摘要: A method for inspecting a laminate structure may include transmitting a lamb wave through a selected portion of the laminate structure from an actuator at a predetermined location on a surface of the laminate structure. The method may also include receiving the transmitted lamb wave at a sensor at another predetermined location on the surface of the laminate structure. The method may additionally include detecting and characterizing an anomaly in the laminate structure based on the received lamb wave.

    摘要: A method and apparatus for inspecting an object is provided. Movement of inspection vehicles relative to a surface of the object is controlled using a controller. Generation of data about the object by sensor systems configured to generate the data when the sensor systems are in a configuration with respect to a location on the object for inspection and receiving power from the inspection vehicles is controlled using the controller. The data generated by the sensor systems is stored.

    摘要: A method for generating an image of an anomaly may include generating a pulse wave into a structure being evaluated from each of a plurality of sensors and collecting any scattered wave data caused by the pulse wave impacting an anomaly. The scattered wave data may be collected by the same sensor that generated the pulse wave or by a different sensor. The method may also include identifying any backscattered wave data from a distal edge or border of any anomaly relative to a location of the sensor collecting the scattered wave data. The method may additionally include processing the backscattered wave data from each of the sensors collecting the scattered wave data to generate a two dimensional image of any anomaly. The method may further include presenting the two dimensional image of any anomaly.

    摘要: A method for quantifying damage in a test structure having a plurality of transducer units coupled to at least one portion of the test structure includes: (a) training an evaluating algorithmic system coupled with the transducer units to establish a trained algorithmic system able to recognize a plurality of characteristics of signals traversing a plurality of paths through a training structure substantially similar to the test structure after the training structure is damaged. Each path is situated between a respective pair of transducer units coupled to the training structure; the plurality of characteristics relates each path to a plurality of physical aspects of the damage. A trained algorithmic system is employed to recognize the plurality of characteristics of signals traversing paths in the test structure to effect the quantifying. The plurality of physical aspects includes less than ten physical aspects.
