Phased array ultrasonic detection device and detection method for shallow surface cracks of locomotive wheels

Abstract

The invention provides a phased array ultrasonic detection device and a detection method for shallow surface cracks of locomotive wheels. Which comprises a probe mechanism (1), a mechanical movement mechanism (2) and a full-focusing phased array ultrasonic detection subsystem (3), and is characterized in that the probe mechanism (1) is connected with the mechanical movement mechanism (2), and the probe mechanism (1) and the mechanical movement mechanism (2) are respectively communicated with the full-focusing phased array ultrasonic detection subsystem (3) through cables. According to the phased array ultrasonic detection device for the shallow surface layer cracks of the locomotive wheels, the working method is based on a full-focusing phased array detection technology, sparse optimization design is conducted on the ultrasonic array through the whale optimization algorithm, the defects, difficult to detect in the prior art, of the shallow surface layer of the locomotive wheels are detected, the detection efficiency is improved, and the detection cost is reduced. The detection blind area is reduced, the detection accuracy is improved, and the detection cost is reduced.
