摘要：In this paper, the exact solutions of PZT coupled electric impedance and structure mechanical impedance were derived with the investigation of the dynamic interaction between the PZT and the host structure. In the frequency range of 0.1-120 kHz, numerical simulation of the PZT coupled electric impedance was performed using MATLAB code. Experimental investigations were conducted with a PZT excitation and electric impedance measurement system developed by our laboratory in the frequency ranges of 30-55 kHz and 80-100 kHz. The profile and resonant frequencies of predicted and measured impedance frequency spectra were in close agreement and the largest deviation is 0.402%.
