Multidomain Vibration-Absorber Design

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）以及在其上运行的动力系统（例如铁路和公路车辆）。为了实现更具结构弹性、低碳和终身成本效益的基础设施资产，减振器的性能迫切需要逐步改变。考虑到来自多个领域（机械、液压、气动和电气）的组件，有许多吸收器设计的可能性。然而，由于没有可用的系统方法，迄今为止只研究了数量极其有限的设计。该研究将建立一个最佳的多域减振器合成工具，这将充分释放减振器设计的巨大潜力。拟议的综合工具的优越性，以及随后的设计改进，将在三个基础设施部门使用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（风能部门）的风力和波浪引起的负荷；减轻建筑物和桥梁（土木结构部门）因环境和人为因素引起的振动；加强车辆-轨道和受电弓-接触网的相互作用（铁路部门）。开发的减振器综合工具将适用于解决各种机械结构的动态性能挑战，例如，最大限度地减少重型车辆产生的道路损伤，减轻液压和气动管道的振动，以及增强机器人和自动驾驶汽车的动态性能。这为PI、英国学术界和英国工业界提供了一个重要的机会，以独特的专业知识在这一具有挑战性的领域建立世界领先的能力。

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.
