摘要
本文研究了含压电作动器和传感器层的复合材料层板理论，建立了位移和电自由度的四节点有限元素，利用总势能最小原理推导了静力平衡方程，实现和验证了含压电作动器／传感器复合材料层板静态分析有限元程序。并对该类复合材料层板进行了形状控制研究。
The theory of composite laminate with distributed actuators and sensors was studied. Based on the study, a four node composite plate element with displacement and electrical degrees of freedom was developed. Then the static equilibrium equations were derived by using the principle of minimum total potential energy. And an FEA code was also implemented and verified to the static analysis of composite laminate containing peizoelectric actuators/sensors. Furthermore, shape control was investigated for such composite plates.
