摘要: This paper describes a generic impedance-based model for predicting the electromechanical (EM) impedance of one-dimensional (1D) and two-dimensional (2D) structure-piezoceramic (PZT) interacting systems. The vibration PZT patch is first analyzed. effect host structure then represented by its force impedance, which obtained semianalytical method. Finally, experiments are carried out on beams plates to simulate 1D 2D problems, respectively. It found that predicted EM structure-PZT system coincides very well with experimentally measured data. results show peaks match natural frequencies structure. small shift from caused interaction between indicates size can be permanently bonded on-line health monitoring without changing mechanical properties structu...
