Description
Technical field
The invention belongs to the pulse reflection ultrasonic shear waves detection field in Dynamic Non-Destruction Measurement, be specifically related to a kind of Ultrasonic Detection voussoir.
Background technology
In Ultrasonic Detection process, acoustic beam refraction angle determines the direction of propagation of shear wave acoustic beam, only have when the direction of propagation of shear wave Main beam is vertical with defect extension direction, ultrasonic probe just can receive the strongest defect reflection echo signal, therefore, the selected of acoustic beam refraction angle has a significant impact ultrasonic testing results.
The shear wave list probe at what current Ultrasonic Detection adopted is fixing refraction angle, detects the needs of operating mode, selects the probe at different acoustic beam refraction angle to detect according to reality.The refraction angle of this ultrasonic shear waves probe is discrete, and the acquisition cost of the series probe at different acoustic beam refraction angle is high, and the utilization factor of single shear refraction angle probe is low.
Summary of the invention
