Abstract
The present disclosure concerns an ultrasonic excitation arrangement (100) comprising a high-power ultrasonic transducer (10) and a housing (20), the housing (20) defining a volume of space (21) for accommodating an ultrasound-transmitting medium (22). The housing (20) is adapted such that, in use, the ultrasound-transmitting medium (22) receives ultrasound (1) emitted by the high-power ultrasonic transducer (10), and a test structure (30) receives the ultrasound (1) from the ultrasound-transmitting medium (22). As a result, high-amplitude guided waves can be uniformly excited on the test structure (30), and this allows extended guide-wave inspection ranges.
Claims30
Ultrasonic excitation arrangement comprising:
- a high-power ultrasonic transducer;
- and,
- a housing, the housing defining a volume of space for accommodating an ultrasound-transmitting medium,
- wherein the housing is adapted such that, in use, the ultrasound-transmitting medium accommodated in the housing receives ultrasound emitted by the high-power ultrasonic transducer, and such that a test structure being tested using the ultrasonic excitation arrangement receives the ultrasound from the ultrasound-transmitting medium.
