Abstract

The invention belongs to a nondestructive detection technology and relates to an adaptive ultrasonic tracking and scanning array transducer, which is applied to the automatic ultrasonic scanning and nondestructive detection of medium and large composite material and metal material structures in the fields of aviation, spaceflight, electronics, weapons, ships, metallurgy, steel, traffic, construction and the like. The transducer comprises a probe boot protective cover, a probe boot bracket, a probe boot pedestal, an adaptive ultrasonic transducer unit and a coupling water path. A multi-channelultrasonic array transducer is used, a scanning area in unit time is improved, the detecting efficiency of composite material members and the like is greatly improved, and the detecting efficiency can be improved by orders of magnitude compared with that of the traditional single-channel automatic ultrasonic scanning and detecting equipment, and can be improved by at least 50 times compared with that of manual scanning and by 20 times compared with that of the traditional single-channel automatic ultrasonic scanning and detection during 20-channel detection.

Description

technical field [0001] The invention belongs to the non-destructive testing technology, and relates to an ultrasonic adaptive tracking scanning for the non-destructive testing of large-scale composite materials and metal material structures in the fields of aviation, aerospace, electronics, weapons, ships, metallurgy, steel, transportation, construction, etc. array transducer. Background technique [0002] Ultrasonic pulse vertical longitudinal wave reflection / penetration method is an important non-destructive testing method adopted in the world at present. non-destructive testing. The transducer is the key unit of ultrasonic testing, mainly used to transmit / receive ultrasonic waves. During the testing process, it must be ensured that the incident direction of the sound waves generated by the transducer is consistent with the normal direction of the detected point of the part, in order to realize the normal transmission / reception of ultrasonic waves. Usually, it is necessa...
