AI Technical Summary
Existing technologies for ultrasonic guided wave testing of railway rail components lack multi-channel active control methods for different modes, making it difficult to achieve selective excitation and energy focusing of specific modes. This leads to increased complexity in signal analysis and affects the accuracy of defect identification.
By optimizing the arrangement and excitation method of the multi-channel transducer array and combining it with the characteristics of the modal displacement field, selective excitation and energy focusing of the target mode can be achieved. By actively controlling the time delay and phase of the multi-channel transducer array, the signal processing difficulty can be reduced and the detection sensitivity can be improved.
It significantly improves the detection accuracy and signal-to-noise ratio of railway rail components, enhances the ability to identify defects, and is suitable for condition assessment and damage detection of rail components with complex cross-sections.
