摘要
Using distributed PZT transducer, ultrasonic guided waves are generated and received in a pipe. Because multiple modes of guided wave propagation are possible in pipes and these modes are generally dispersive, the specific exciting signal of a Hanning windowed toneburst with a central frequency of 70 kHz is selected for decreasing the effect of dispersion. And guided waves are generated using 16 distributed PZT transducer in a circumferential direction for suppressing flexural modes. The experimental results are good agreement with the theoretical ones.
