| 摘 要： | 智能结构技术对空间大型柔性结构 振动控制问题具有重要意义，采用独立模态空间控制技术对压电智能板进行主动振动控制是一种常用方法，以前对这一问题的研究仅限于解析的方法，本文采用有限单元法，设计了新的压电模态传感器与致动器，该方法能够适用于形状及边界条件较为复杂的智能板，算例分析证明了该方法的正确性。

| Abstract: | The technology of smart structures is significant for the vibration control of large flexible space structures. Although it is usual to actively control the vibration of piezoelectric smart plates by independent modal space control method, the previous solutions are limited to analytical methods. A new design technology of modal sensor and actuator developed in this paper by finite element method, which is suit for the plate with complex shape and boundary conditions. The results of studies verified its validation. |
