Simulation of Scattering Acoustic Field in Rod and Identify of Ultrasonic Flaw Detecting Signal
A method of acoustic field simulating was proposed, in this paper, the authors simulated the scattering acoustic field generated by impulsive line source in a glass rod, and compared the results with the dynamic photoelastic experiments, explained the forming mechanism of the scattering wave (e.g. the boundary wave) of ultrasonic flaw detection in rod. Based on this, the serial echo signal of the flaw detection in rod by single transducer was identified, and a signal processing method was suggested. According to these, using single transducer, testing one time, lots of mechanical property could be analyzed.
