摘　　要：本文分析由压电材料进行控制的复合层合梁,利用哈密顿原理分析压电效应与结构变形的耦合作用,考虑到电场条件对结构变形的影响,推导出压电层合梁的运动方程,并求得了压电层合梁固有特性与电场的关系.并以两端简支层合梁为算例进行分析,并将计算结果与实验结果进行比较,从而证明了本文分析方法的正确性.The vibration of a composite beam, embedded with piezo-electric film, is analysed in the paper, Hamilton principle is made in use to analyse the coupled effect between piezo-elec-tricity and structure deformation,considering the influence of electric field on deformation, the e-quation of motion of a composite beam is derived. A simply supported composite beam is taken as an example. The good conformance between the results of numerical analysis and test verifies the correctness of the analysis procedure.
