| 摘 要： | 导出压电薄板的传递函数模型,建立起压电结构与一般结构模态控制的类比关系。基于此,结合实验研究,提出“准独立模态控制”方法,能在尽可能简单的硬件条件下逼近独立模态控制目标。多模态阻尼控制实验进程和结果表明了它的有效性和实用性。

| Abstract: | A transfer function model of piezoelectric thin plates is derived and an analogy for modal control between the piezoelectric structures and general ones is established. Based on this concept and by experiment development, a "quasi independent modal control" technique is presented, attempting to approach, with hardware as simple as possible, independent modal control. The experiment progress and results for multiple modal damping control show its effectiveness and practicality. |
