Acoustic Black Holes for Control of Structural Vibration and Sound Radiation

声学黑洞(ABHs)是基于对结构引入精心设计的几何特征，已被证明在梁和板上都能实现显著的结构减振水平。该项目的目的是开发ABHs的设计、优化和实际实施，从而促进其在复杂实用结构中的开发。特别是，该项目可能会研究多个ABH之间的相互作用，并探索优化其在复杂结构上的位置的方法，以将结构振动或声辐射降至最低。此外，还可以探索将主动技术集成到ABH的设计中。研究的具体重点可能取决于成功候选人的技能和兴趣，但将涉及理论、数值和实验研究的混合。

Acoustic black holes (ABHs), which are based on introducing carefully designed geometrical features to a structure, have been shown to achieve significant levels of structural damping in both beams and plates. The aim of this project is to develop the design, optimisation and practical implementation of ABHs and, therefore, facilitate their exploitation in complex practical structures. In particular, the project may investigate the interaction between multiple ABHs and also explore methods of optimising their locations on complex structures to minimize either structural vibration or sound radiation. Additionally, the integration of active technologies into the design of ABHs may also be explored. The specific focus of the research is likely to depend on the skills and interests of the successful candidate, but is will involve a mixture of theoretical, numerical and experimental investigation
