Abstract：X-ray digital radiography detection method has been widely used in many fields of industrial production, and has become an important detection method of composite honeycomb sandwich structure. For large composite honeycomb sandwich structure, it is necessary to improve the detection efficiency of X-ray digital radiography. According to the characteristics and detection requirements of large composite honeycomb sandwich structure, an automated scanning imaging detection method of X-ray digital imaging was proposed, and the design characteristics and parameter selection of key units of the automated scanning detection system for large composite honeycomb sandwich structure were introduced. Using the developed X-ray digital imaging automatic scanning detection equipment, the determined detection parameters and the actually designed and prepared large honeycomb sandwich structure, a series of testing experiments were carried out. The experimental and practical application results show that the X-ray digital imaging automatic scanning detection method can realize the rapid visual detection of large honeycomb sandwich structure, the detection resolution can reach 3.2 LP/mm, and obtain a good detection effect.
