论文摘要
这项工作提出了一种新方法来设计电网,当通过一系列压电传感器耦合到结构时,可提供多模式振动缓解。网络的特征是根据模态性能指定的。一方面,选择电气共振频率接近靶向结构模式的集合。另一方面,选择电气模式形状以最大程度地提高机械机械耦合,同时保证网络的被动性。使用免费的光束和完全夹紧的板证明了这种基于模态合成的有效性。
This work presents a new approach to design an electrical network which, when coupled to a structure through an array of piezoelectric transducers, provides multimodal vibration mitigation. The characteristics of the network are specified in terms of modal properties. On the one hand, the electrical resonance frequencies are chosen to be close to those of the targeted set of structural modes. On the other hand, the electrical mode shapes are selected to maximize the electromechanical coupling between the mechanical and electrical modes while guaranteeing the passivity of the network. The effectiveness of this modal-based synthesis is demonstrated using a free-free beam and a fully clamped plate.
