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
The transfer function model of the piezoelectric thin plate is derived and the analogy between the piezoelectric structure and the general structure modal control is established. Based on this, combined with experimental research, a “quasi-independent modal control” method is proposed, which can approach independent modal control objectives under the simplest hardware conditions. Multi-modal damping control experimental process and results show its effectiveness and practicality
