【摘要】 埋置于混凝土中的压电陶瓷片可用于混凝土结构的无损监测 ,而其自身的力学行为可视为一周边固定的复合薄圆板的振动。由于所研究的压电陶瓷片是由压电陶瓷层和薄铜片两种不同材料所组成 ,因此不仅存在自由度的耦合问题 ,同时还存在不同物理场的耦合问题。本文利用ANSYS6 1对所研究的压电陶瓷片进行了压电耦合分析 ,并得出了其正反谐振模态更多还原

【Abstract】 The piezoelectric ceramic piece which placed in the concrete can be used in the monitoring of the concrete structure, and its mechanical action may see as a vibration of compound thin disc. This piezoelectric ceramic piece is composed of two kinds of different materials, there exits coupling question of degree of freedom, and the coupling of different physical field. This article uses the ANSYS6.1 to carry on the coupling analysis of piezoelectricity, and finds out its positive and negative resonance simulating model.更多还原
