摘　　要：本文从机电耦合弹性体的理论出发，运用Ｈａｍｉｌｔｏｎ原理建立了一般压电耦合系统的动力分析模型，并给出了模态分析和有限元分析的耦合系统方程、作动方程及检测方程。该分析模型和计算公式可用于任意形状压电耦合系统的动力分析和振动控制设计。另外，导出的模态分析和有限元公式可用现有的商业软件求解。Based on the theory of mech-electric coupling elasticity and by using Hamilton's principle,the dy-namic analytical model of general structural-piezoelectric coupling system is developed , and the appro-priate equation of motion of the coupling system, actuating equation and sensing equation for bothmodal analysis and FEA are derived. The model and formulas can be used in both dynamic analysisand vibration control design of any piezoelectric coupling system.In addition,the formulas of modalanaiysis and FEA can be solved by standard structural dynamic analysis software.
