To solve the problem that the rectangular Terfenol-D oscillator cannot be coupled with any surface of the pipeline, a new structure is desnd transient response analysis were performed on the oscillator with the new structure, and the length of the oscillator with the new composite igned to combine the U-type base with the Terfenol-D oscillator to make it better coupled with the pipeline. Numerical simulation astructure was confirmed to be 25 mm. The same pipe was tested with a 25 mm new structure transducer and a piezoelectric ceramic transducer. The experimental results show that the flaw echo amplitude value of the magnetostrictive transducer with the new structure is 1.5 times that of the piezoelectric ceramic transducer, further verifying the correctness of new composite structure design.

Key words: giant magnetostrictive, ultrasonic guided wave, transducer, composite structure, resonant frequency, numerical simulation
