  • Publication number: 20240192176
    Abstract: A method for analyzing the quality of a first mechanical part comprising determining a measurement data filtering template from information representing an ultrasonic wave reflected in a second mechanical part, called “master” part, when emitting an ultrasonic wave along a predefined application path, then extracting information representing the quality of the first part from information representing the ultrasonic wave reflected in the first part and from the template, the template comprising a plurality of amplitude thresholds of the reflected wave expressed relative to the travel time of the wave in the parts.

  • Patent number: 10201899
    Abstract: A process for marking the real position and real orientation of a tool in relation to the manipulator arm of a robot. The process utilizes the amplitude measurements of acoustic signals and the flight time measurement of the acoustic waves emitted by an acoustic probe of the tool and reflected by the fixed reference elements. The position of the center of reference of the probe relative to the end of the manipulator arm is determined. The axes X and Y defining the plane of the probe along reference axes X? and Y? of known orientations are oriented so that the modification of the position and of the orientation of the probe in the reference frame can be defined. The displacements of the manipulator arm are managed by the controller based on the position of the probe in relation to the manipulator arm and the reference orientation of the probe.

  • Patent number: 9952181
    Abstract: A device for testing a stiffener of an aircraft structure made from composite materials. At least one ultrasound sensor is configured to provide measurements relative to a material health state of the stiffener. The device includes a protective enclosure for housing the ultrasound sensor and a mobile gantry configured to move along the stiffener. The protective enclosure with the ultrasound sensor is mounted inside the mobile gantry. A driver is configured to drive the mobile gantry along the stiffener. A clamper is rigidly connected to the protective enclosure and configured to hold the ultrasound sensor pressed against the surface of the stiffener to be controlled. A locator to synchronize each area of the surface of the stiffener with the measurement of the ultrasound sensor.

  • Publication number: 20160266071
    Abstract: A device to hold a piece for an item of equipment for ultrasonic measurement. This device has a hollow body, which is substantially tubular, a first end of which can be applied against a surface of the piece and a second opposite end can be connected to a suction element. The hollow body is made from rigid material and the device includes a peripheral joint associated with the first end.
