Abstract: Under the background of accelerating the cultivation of high-quality digital radiography technology talents, in order to solve the problems of high complexity, few equipment sets, and insufficient class hours in X-ray DR imaging testing, a virtual simulation experimental teaching platform for X-ray DR imaging testing of aviation complex components was developed based on virtual simulation technology. A three-level virtual simulation experimental teaching design of foundation-application-improvement was constructed, through the development of comprehensive experimental content, diversified experimental teaching methods, and inspection process evaluation. It effectively supports the cultivation of students’ engineering practical ability and innovative ability, further improvement is needed in the construction of virtual simulation platforms to enhance training effectiveness.
