AI Technical Summary
There are few studies on multi-parameter synchronous detection in existing technologies, making it difficult to effectively characterize changes in material properties.
An electromagnetic ultrasonic surface wave multi-parameter synchronous detection sensor is designed, which adopts an excitation end magnet group and a receiving end magnet group with parallel magnetic poles arranged in opposite directions, combined with a folded excitation coil, a vertical rectangular receiving coil and a horizontal racetrack-shaped coil to realize the multi-parameter synchronous detection of surface waves.
It enables the assessment of material aging damage and the degree of material degradation, and improves the efficiency and accuracy of detection through multi-parameter analysis.
