摘要
提出了一种新的压电结构有限元分析方法，即压电薄板立体单元法。利用哈密顿原理推导出压电结构的变分方程，建立了智能结构的有限元动力方程。并以具有压电薄层的层合板为例进行了研究，证明了本文所用方法简单。
s:In this Paper,a new finite element analytic method of piezoelectric structures is proposed.Hamilton′s principle is used to derive the equation of piezoelectric thin films and the dynamic finite element equations of intelligent structures.A laminated plate with two distributed piezoelectric films is studied.Then the correctness of this method is proved.
