Intelligent Structures for Low Noise Environments

在各种工业应用中，振动结构的噪声和振动辐射是一个主要问题。这一研究项目的特别应用重点是海事系统，在这些系统中，主要和辅助机械可能会造成与船员和乘客舒适性、结构完整性相关的问题，而且越来越多的辐射噪声被视为对海洋生物的危害。虽然在实践中使用了一系列被动振动和噪声控制措施，但它们不能在低频率下提供有效的控制。该项目是一个更大的研究计划的一部分，该计划的重点是为一系列噪音和振动控制问题开发创新和有效的解决方案。这包括有源噪声和振动控制解决方案、先进的无源噪声控制技术，如超材料和声学黑洞，以及使用设计和拓扑优化方法设计低噪声结构。该计划还将研究如何优化噪声和振动控制系统以满足主观性能，并考虑如何将振动控制和采集整合到统一的设计方法中。虽然整个研究计划范围很广，但这个博士项目在更大的计划内的具体重点将在一定程度上取决于候选人以前的经验、兴趣和未来的潜力-我们正在寻找最有前途的研究人员，他们将能够为开发用于低噪音环境的新颖和智能结构和系统的目标做出贡献。

The radiation of noise and vibration from vibrating structures is a major problem in a wide variety of industrial applications. The particular application focus for this research project is in maritime systems, where the main and auxiliary machinery can cause problems associated with crew and passenger comfort, structural integrity and where increasingly radiated noise is seen as a hazard for marine life. Although a range of passive vibration and noise control measures are used in practice, they do not provide effective control at low frequencies. This project is part of a larger research programme, which focuses on the development of innovative and effective solutions for a range of noise and vibration control problems. This includes active noise and vibration control solutions, advanced passive noise control technologies, such as Metamaterials and Acoustic Black Holes, and the use of design and topology optimisation methods for the design of low noise structures. The programme will also investigate how noise and vibration control systems can be optimised for subjective performance and consider how control and harvesting of vibration can be integrated into a unified design approach. Although the overall research programme is broad, the specific focus of this PhD project within the larger programme will depend to a certain extent on the candidates previous experience, interests and future potentials - we are seeking the most promising researchers that will be able to contribute to the objective of developing novel and intelligent structures and systems for low noise environments.
