摘要
采用板的一阶剪切变形理论,对含有压电材料层的复合材料层合板,从机电耦合的变分方程及 Hamilton 原理出发,建立起求解其动态响应的有限元方程。同时也给出了压电材料层作为传感元件时的传感方程及作为作动元件时的作动方程。并采用速度反馈控制实现了层合板的主动振动控制。最后给出了计算实例。
In this paper,by using the first order shear deformation theory for anisotropic plate in addition with mechanical-electro coupled variation equation and Hamilton principle,a two dimensional dynamic fi- nite element formulation for composite laminates containing piezoelectric layers was derived.Simutaneous- ly the piezoelectric sensor and actuator equations are also attained.By means of velocity feedback control agolrithm the active vibration control of laminates is fulfilled.Finally several numerical examples are pre- sented to show the vitality of the present approach.
