SAMPLE TEST DRIVE Wheel ULTRASOUND

摘要

The invention relates to devices for testing ultrasonic flaw sensitive elements - of probes used to study objects of complex shape, e.g., railroad rails. The sample can be used in the manufacture and operation of ultrasonic wheel transducer. The test specimen ultrasonic wheel transducer is made in the form of a wheel, rotatably about an axis, the wheel rim has a cross section that coincides with the cross-sectional profile of the rail and the wheel rotation axis and perpendicular to the symmetry of the cross section. The longitudinal rail axis lies in the same plane, so this sample more favorably used for testing probes in a single wheel or ultrasonic EMAT. Thus through the resulting contact pattern between the elastic shell surface ultrasonic wheel transducer and the test sample is reliably ensured administered under ultrasonic oscillations required angles. The sample can be used for dynamic testing of ultrasonic probes during their manufacture and operation.
