Abstract:Aiming at the problem of jumbled data and time-consuming detection of traditional mechanical materials, combined with the structural characteristics of mechanical materials, an image-based X-ray testing technology for mechanical materials is proposed. This paper introduces the basic principle of X-ray detection, then designs an X-ray detection system, preprocessing and tilt correction of the collected mechanical material image, and establishes the imaging system model to determine the imaging azimuth. To justify the effectiveness of the proposed method, simulation is carried out on the platform of Matlab2016b, and 5 kinds of mechanical materials are selected for defect comparison test. The results show that the proposed method can accurately detect the defects of mechanical materials, the detection time is short, the detection efficiency is improved, and can be applied to the image detection of mechanical materials.
