| Flexible array ultrasonic nondestructive testing system |
| Function summary |
| Flexible array ultrasonic nondestructive testing system consists of flexible two-dimensional array transducer, multichannel transceiver apparatus and computer. It can realize real-time imaging of surface microdefects of the curved surface components. |
| Technical features |
| Small array element size, flexible structure, adapting to the shape of tested components, no problem of coupling, large signal amplitude. |
| Hardware control, realizing the control of each array transducer element, no need to move the transducer |
| Real-time B scan imaging of the curved surface, clearly showing the locations of defects, high resolution and high detection efficiency. |

| Specifications |
| Equivalent detectable defect area on the curved surface: 0.1×5mm |
| Technical principl |
| Based on the principle of guided wave propagation and the modal control, single-mode guided wave can be simulated by the two-dimensional array transducer. Using the principle of phased array, the scanning and imaging of the curved surface can be obtained. |
| Applications |
| It can be applied to plate parts defects detection,gear tooth root micro cracks detection and curved surface components scanning and imaging testing. |
