摘要:
An ultrasonic detection method and system are disclosed. The ultrasonic detection method includes providing an ultrasonic detection system 100 having a first ultrasonic device arrangement 102 and a second ultrasonic device arrangement 104, positioning the ultrasonic detection system 100 in a peripheral offset position with respect to an object 106 to be measured, and transmitting and receiving an ultrasonic beam between the first ultrasonic device arrangement 102 and the second ultrasonic device arrangement 104, thereby obtaining ultrasonic detection information about the object 106. Additionally or alternatively, the transmitting and receiving of the ultrasonic detection method obtains data on a volume greater than that which is capable of being analyzed by a single probe arrangement. The ultrasonic detection system 100 includes the first ultrasonic device arrangement 102 and the second ultrasonic device arrangement 104 positioned in a peripheral offset position with respect to an object 106 to be measured.

In an electrochemical machining tool assembly having at least one electrode (26) arranged across a gap (34) from a workpiece (12), the electrode being energized by application of a potential difference ΔV between the electrode and the workpiece, a method of monitoring machining includes exciting at least one ultrasonic sensor (42) to direct an ultrasonic wave toward a surface (102) of the electrode and receiving a reflected ultrasonic wave from the surface of the electrode using the ultrasonic sensor. The reflected ultrasonic wave includes a number of reflected waves from the surface of the electrode and from a surface of the workpiece. The method further includes delaying the excitation of the ultrasonic sensor a dwell time T d after a reduction of the potential difference ΔV across the electrode and the workpiece occurs.

The present disclosure provides for the application of a two-dimensional ultrasonic phased array (100), formed of a plurality of transducers (102) arranged in a rectilinear pattern, for material and volumetric component testing. The two-dimensional array enables electronic adjustment of the focal properties and size of the aperture (104) in both the azimuthal (X) and elevational (Z) directions such that uniform and/or specified sound field characteristics can be obtained at any or all locations in the component being tested.

A method for inspecting a component (10) includes exciting a number of transducers (12) forming an array (14) to produce an ultrasonic transmission beam (beam) focused into the component. The array and the component are separated by a standoff (18). A number of echo signals are generated using the transducers, and the echo signals are processed in a number of channels. The processing includes both dynamical focus and providing a dynamic aperture (24) on receive, both of which compensate for refraction of the beam at the component/standoff interface. A single-turn inspection method includes: (a) positioning the array facing the component, (b) exciting the transducers, (c) generating a number of echo signals, (d) changing the relative angular orientation of the array and the component around an axis (26) and repeating steps (b) and (c), and (e) processing the echo signals to form at least one processed echo signal.

摘要:
A system (10) and method for radiographic inspection of aircraft fuselage (12)s includes a radiation source (28) preferably located inside of the fuselage (12) and a radiation detector (32) preferably located outside of the fuselage (12). A source positioning system (30) is provided for moving the radiation source (28) longitudinally with respect to the fuselage (12), and a detector positioning system (34) is provided for positioning the radiation detector (32) in longitudinal alignment with the radiation source (28). The detector positioning system (34) also moves the radiation detector (32) circumferentially with respect to the fuselage (12). In operation, the radiation detector (32) is moved over the fuselage (12) in a circumferential direction while the radiation source (28) illuminates an adjacent region of the fuselage (12) with radiation.
