Vibration absorbers are commonly used in infrastructure assets (e.g. wind turbines, buildings, bridges) and in the dynamic systems which operate on them (e.g. railway and road vehicles). To achieve more structurally resilient, low carbon and lifetime cost efficient infrastructure assets, a step change in the performance of vibration absorbers is urgently needed. There are numerous absorber design possibilities considering components from multiple domains (mechanical, hydraulic, pneumatic and electrical). However, because there is no systematic approach available, only an extremely limited number of designs have been studied to date. This fellowship will establish an optimal multidomain vibration-absorber synthesis tool, which will fully unlock the significant potential of vibration absorber designs.The superiority of the proposed synthesis tool, and the subsequent design improvements, will be demonstrated using industrially driven and supported case studies in three infrastructure sectors. These include the alleviation of wind- and wave-induced loads to wind turbines (wind energy sector); the mitigation of environmental- and human-induced oscillations in buildings and bridges (civil structure sector); the enhancement of vehicle-track and pantograph-catenary interactions (rail sector).The developed absorber synthesis tool will be applicable to solving the dynamic performance challenges in a wide range of mechanical structures, for example, minimising road damage produced by heavy duty vehicles, vibration mitigation of hydraulic and pneumatic pipelines, and dynamic performance enhancement for robotics and autonomous vehicles. These present a significant opportunity for the PI, UK Academia and UK Industry to establish a world leading capability in this challenging field with unique expertise.

减振器通常用于基础设施资产（例如风力涡轮机、建筑物、桥梁）和在其上运行的动态系统（例如铁路和公路车辆）。为了实现结构更有弹性、低碳和寿命成本效益更高的基础设施资产，迫切需要减振器性能的阶跃变化。考虑到多个领域（机械、液压、气动和电气）的组件，有许多减振器设计可能性。然而，由于没有系统的方法，只有一个非常有限的设计进行了研究。该奖学金将建立一个最佳的多域减振器综合工具，这将充分释放减振器设计的巨大潜力。所提出的综合工具的优越性，以及随后的设计改进，将通过三个基础设施领域的工业驱动和支持的案例研究来证明。这些措施包括减轻风力涡轮机的风力和波浪引起的负荷（风能部门）;减轻环境和人为引起的建筑物和桥梁振动（土木结构部门）;车辆-轨道和弓网相互作用的增强（铁路部门）。所开发的吸收器综合工具将适用于解决各种机械结构中的动态性能挑战，例如，最大限度地减少重型车辆对道路的破坏，减轻液压和气动管道的振动，以及提高机器人和自动驾驶车辆的动态性能。这为PI，英国学术界和英国工业界提供了一个重要的机会，可以在这个具有挑战性的领域建立世界领先的能力，并拥有独特的专业知识。
