| 摘 要： | 基于四节点压电复合材料层合板单元和相应有限分析方法，利用结构位移对电压的灵敏度，对以压电材料为作动器的板壳自适应结构，进行了考虑平整性要求的静力变形控制。根据控制目标和约束限制，由数学规划问题确定结构承载时作动器所需的控制电压，最后以数值算例给出了仿真结果，以验证所提出方法的有效性。

| Abstract: | Based on the 4 nodes element used for piezoelectric composite laminate plate and finite element method,and using sensitivities of structural displacements with respect to actuator voltages,the static deformation control considering smoothness requirement for platelike adaptive structure with piezoelectric material layers as actuators is studied in this paper.According to the control objective and constraints,the required actuator voltages to control the loaded structures are determined with mathematical programming problems.Simulation results are finally given here through numerical examples to verify the effectiveness of the proposed method. |
