【摘要】 如果把压电材料作为复合材料层合板的铺层之一，层合板就变成所谓的压电自适应层合板，它除了具有承载能力外，还具有检测、动作等功能。本文用有限元法对压电自适应层合板进行了分析，压电元件的驱动效应被等效为力学载荷，从而实现了压电层合板的机－电耦合问题的解耦，所得计算结果和实验结果非常符合。更多还原

【Abstract】 If piezoelectrical material has been used as one of the layers of composite material laminate,the laminate becomes so called piezoelectrical adaptive one,which not only has the load bearing capacity,but also has the measuring and actuating capacity.In this paper,the piezoelectrical adaptive laminate is analyzed with the finite element method,and the actuating effect of piezoelectrical element is changed for a equivalent mechnical load,this load to uncoupling of the mechanical electrical couple,the computational results satisfy the experimental ones.更多还原
