摘要

元结构是由称为谐振器的相同组件的周期性阵列组成的工程系统,旨在实现特定的动态效果,例如产生带隙-波不能通过结构传播的频率范围。当配备了压电材料片时,这些元结构表现出额外的能力:它们甚至可以从远低于单个谐振器基本频率的频率中有效地收集能量。这种能量收集能力对于低频振动占主导地位的应用特别有价值。为了支持双重目的元结构的设计,例如能量收集和振动抑制(减少结构中不必要的振荡),我们开发了一个压电能量收集器的多补丁等几何模型。该模型基于Kirchhoff-Love压电板(一种嵌入压电片的薄而灵活的结构),并使用Nitsche的方法在不同片的边界上执行位移、旋转、剪切力和弯矩方面的兼容性条件。根据文献中的实验数据和数值数据对模型进行了验证。然后,我们提出了一种新颖的参数化元结构板设计,并进行了参数化研究,以探索谐振器几何形状如何影响关键性能指标,包括带隙的位置和宽度以及电压频率响应函数中第一个峰值的位置。该模型可以与优化算法集成,根据应用需求最大化能量收集效率或减振等结果。

Design of piezoelectric metastructures with multi-patch isogeometric analysis for enhanced energy harvesting and vibration suppression
Metastructures are engineered systems composed of periodic arrays of identical components, called resonators, designed to achieve specific dynamic effects, such as creating a bandgap-a frequency range where waves cannot propagate through the structure. When equipped with patches of piezoelectric material, these metastructures exhibit an additional capability: they can harvest energy effectively even from frequencies much lower than the fundamental frequency of an individual resonator. This energy harvesting capability is particularly valuable for applications where low-frequency vibrations dominate. To support the design of metastructures for dual purposes, such as energy harvesting and vibration suppression (reducing unwanted oscillations in the structure), we develop a multi-patch isogeometric model of a piezoelectric energy harvester. This model is based on a piezoelectric Kirchhoff–Love plate – a thin, flexible structure with embedded piezoelectric patches – and uses Nitsche’s method to enforce compatibility conditions in terms of displacement, rotations, shear force, and bending moments across the boundaries of different patches. The model is validated against experimental and numerical data from the literature. We then present a novel, parameterised metastructure plate design and conduct a parametric study to explore how resonator geometries affect key performance metrics, including the location and width of the band gap and the position of the first peak in the voltage frequency response function. This model can be integrated with optimisation algorithms to maximise outcomes such as energy harvesting efficiency or vibration reduction, depending on application needs.

期刊介绍: The Journal of Sound and Vibration (JSV) is an independent journal devoted to the prompt publication of original papers, both theoretical and experimental, that provide new information on any aspect of sound or vibration. There is an emphasis on fundamental work that has potential for practical application. JSV was founded and operates on the premise that the subject of sound and vibration requires a journal that publishes papers of a high technical standard across the various subdisciplines, thus facilitating awareness of techniques and discoveries in one area that may be applicable in others.
