| Complex component ultrasound scanning |
| Function Summary |
| Complex component ultrasound scanning system is suitable for the plane scanning, the revolved body scanning, the large-scale curved component scanning, and the rotation scanning for pipes and rods. The system uses a single probe sending and receiving ultrasound at the same time to achieve the nondestructive testing of the tested workpiece. The detection system, based on acoustic emission technique, can achieve complex component testing and high speed automation residual stress testing at the same time. |
| The testing system adopts the self-development robot motion control system and the self-development ultrasonic monitoring system. The system has very good adaptability and extensibility, and, through the conversion of the manipulator end, can realize multiple scanning methods such as water coupling scanning, air coupling scanning, etc. A C-scan image can be generated after the acquisition and processing the ultrasonic signals, and the image can directly show the details of the workpiece internal defects and the distribution of the residual stress. |

| Technical principle |
| Complex component ultrasonic scanning system consists of the manipulator body structure, the motion control system, the acoustic emission and receiving system and the software system. The scanning process is accomplished by the motion control card controlling the manipulator. The dynamic space of the general purpose manipulator is flexible, which can realize complex position postures and is particularly suited to guarantee the acoustic axis vertical to the curved surface of the complex workpiece. The ultrasonic pulse transmitting and receiving process is completed by the pulse sending and receiving card in the industrial computer, and the collected data are then transmitted to the computer for display, storage and processing. |
