Reducing maintenance costs while increasing the safety and reliability, especially in moving structures, needs a reliable nondestructive analyzer. The aim of this research is to provide a practical solution for this problem, which works based on high-frequency excitation of stationary and moving structures by propagating standing Lamb waves in the range of 1 to 1000 kHz. The proposed solution comprises of a controlled frequency swept signal source, a number of piezoelectric sensors, a portable analyzer, and a rotary mechanism. Measuring the accurate electromechanical impedance (EMI) is made possible by monitoring the applied voltages, currents, and phase differences, accurately. In this study, design and implementation of a low-cost, compact and portable transceiver is explored for periodic structural health monitoring of a proposed rotary structure using EMI technique. The compactness of the proposed system is an essential requirement for rotary structures as compared to bulky, heavy and expensive laboratory-type impedance analyzers. Challenges in design and development of such a system are discussed in this paper, together with mitigations to make the system functional and practical. An experimental study is carried out directly in frequency domain to measure the real and imaginary parts of impedance spectrum of piezo-transducers. Stationary experiments are first carried out on an aluminum plate 5083. Having ensured of the transceiver accuracy, a turbomachine prototype which is able to work at up to 3000 rpm and 300 °C is introduced to perform tests on a rotary structure. Damage detection is investigated for pristine and damaged superalloy blades considering the sensible change in mechanical stiffness of the blades. The proposed transceiver is calibrated with a standard impedance analyzer. The results show that the portable transceiver has the capability to detect structural incipient damages before any catastrophic failure, thus avoiding undesirable shut down during the operation.
