Abstract:
Modal unity and attenuation characteristics are important indicators of the incentive effects of guided wave.A guided-wave excitation system is established in which the PZT-5 wafers are symmetrical distributed at one end of the pipeline.In order to reduce the modal unity and attenuation characteristics,experiments have been conducted to study the effect of PZT wafer and modal characteristics on the T(0,1) mode.The optimal scheme to excitation of T(0,1) mode is obtained.
Key words: ultrasonic guided wave;PZT wafer;pipeline inspection;torsional mode
