Application of KLM Model for an Ultrasonic Through-Transmission Method
KLM model has been widely used for designing PZT based ultrasonic transducers by using an ultrasonic pulse-echo method in the field of non-destructive testing. In this study, to apply the KLM model for an ultrasonic through-transmission method, transmitting and receiving ultrasonic transducers, which have different resonance frequency, were simulated and acquired the through-transmitted ultrasonic waveforms. To verify and analyze the KLM model based ultrasonic through-transmission method, an ultrasonic through-transmission system including PZT based ultrasonic transducers, pulser/receiver, a test specimen was constructed and compared with through-transmitted response signals of fabricated ultrasonic transducers based on the same conditions of the KLM simulation.
