    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: In einer Vorrichtung zur Inspektion gefüllter Behälter (1) auf etwaige Fremdkörper (2) wird der gefüllte Behälter durch Vibration oder Rotation mechanisch angeregt, um die ggf. vorhanden Fremdkörper in Bewegung zu versetzen. Die durch Stöße der Fremdkörper mit der Behälterinnenwand entstehenden akustischen Signale werden erfasst und ausgewertet. Erfindungsgemäß wird dabei die Signaldetektion von der mechanischen Anregung und die mechanische Anregung vom Transport der Behälter getrennt, indem der Sensor (3) zur Signaldetektion erst nach Abschluss der mechanischen Anregung an den Behälter angelegt wird, bzw. die mechanische Anregung durch ein Anregungselement (6, 7) erfolgt, das unabhängig von den für den Transport verwendeten Halteelementen (5) mit dem Behälter (1) in Kontakt gebracht wird.
