采用自适应结构的原理和方法,对压电元件用于挠性结构振动控制的一些问题进行了探讨。对压电驱动器与结构的匹配关系进行了理论分析,对模态传感/驱动器在挠性悬臂板结构中的布置方案进行了优化设计,并进行了结构的振动控制实验。

In this paper, some fundamental problems in the vibration control of flexible structures using piezoelectric ceramics are studied. The matching relationship between piezoelectric actuators and structural matrix is analyzed. The optimal arrangement of collocated modal sensor/actuator in a flexible cantilever plate is discussed. The feasiblity is verified by experiments.
