| 摘 要： | PZT(P iezoe lectric-ceram ic)的EM I(E lectro-m echan ica l im pedance)技术以其适于在线监测的诸多优点受到越来越多的关注。本文系统地阐述了PZT的E/M(电-机)耦合特性、PZT与本体结构的相互作用模型、EM I技术的基本原理及其在土木工程中的研究应用。利用PZT的EM I技术进行健康监测是具有广泛应用前景的一种方法,但由于其研究应用的时间不长,目前仍然处于试验室研究阶段,文中对该项技术中尚需解决的几个问题进行了总结。

| Abstract: | The EMI technique of PZT has received more and more attention due to its merits in adapting to on-line monitoring. The E/M coupling speciality, PZT-structure interaction model, basic principle of EMI technique and the current status of research in civil engineering are presented in this paper. The smart health monitoring method by using PZT technique has potentially extensive usage in the future. However, owing to the short history of the study of EMI technique, the use of this technique is mostly limited in laboratory. Some of the key problems to be solved associated with this technique are summarized in this paper. |
