Abstract

Acousto-ultrasonic input-output characteristics for transmitting and receiving contact-type transducers coupled to a Timoshenko beam are considered. Through introducing some simplifying assumptions for the transducers, an analytical method that can deal with all wave processes involved with the system, i.e., wave generation, wave propagation, and wave reception, is developed. Using this method, the spectral response of the normal contact pressure sensed by the receiving transducer, due to an arbitrary input pulse excited by the transmitting transducer, is expressed in the form of explicit physical interpretations. The time history of the contact pressure output for the receiver is obtained by using the fast Fourier transform technique. Finally, based on the analytical results obtained and large amounts of numerical calculation, the input-output characteristics of the system are discussed. The analysis method can be easily extended to some more general cases, such as those of composite plates and multiple transducers.
