Mitigating unwanted vibration in mechanical structures via effective and reliable approaches is an important and difficult part of the design process. For example, a good balance between ride comfort and handling for passenger vehicles, the need to build taller and more slender buildings while maintaining good dynamic performances under wind and earthquake disturbances, and the trade off between maintaining straight running stability and reducing track wear when curving for railway vehicles, have all attracted much research from both academia and industry. In the current drive for more flexible, lightweight and more efficient structures, enhancing the capability of vibration suppression systems has become even more important.The introduction of the inerter concept has from theoretical point of view fundamentally enhanced the capability of passive vibration suppression systems. Significant theoretical performance advantages for a wide range of mechanical structures have been identified. However, when working on real applications, we face the obstacle of inadequate knowledge of the dynamic properties of physical inerter realisations. This project will establish accurate fluid based inerter models and demonstrate the potential superiority of such designs for passenger cars, tall buildings and railway vehicles through case studies developed in close collaboration with industrial project partners.The proposed work will enable the widespread uptake of fluid inerter based vibration suppression design techniques and constitute a major step towards wide spread application in multiple industrial sectors including road and rail transportation, civil engineering as well as aerospace engineering. The resulting improvements in the UK's capability for advanced design will greatly assist the high-end manufacturing industry to maintain its competitive edge.

通过有效和可靠的方法减轻机械结构中不需要的振动是设计过程中的一个重要和困难的部分。例如，在乘用车的乘坐舒适性和操纵性之间取得良好的平衡，在风和地震扰动下建造更高更细的建筑同时保持良好的动力性能，以及在铁路车辆转弯时保持直线运行稳定性和减少轨道磨损之间的权衡，都吸引了学术界和工业界的大量研究。在当前结构向柔性化、轻量化、高效的方向发展的过程中，提高减振系统的减振能力变得更加重要，惯性减振概念的引入从理论上从根本上提高了被动减振系统的减振能力。广泛的机械结构在理论上具有显著的性能优势。然而，在处理实际应用程序时，我们面临着对物理惰性实现的动态属性了解不足的障碍。该项目将通过与工业项目合作伙伴密切合作开发的案例研究，建立准确的基于流体的惰性装置模型，并展示此类设计在乘用车、高层建筑和铁路车辆上的潜在优势。拟议的工作将使基于流体惰性装置的减振设计技术得到广泛采用，并成为在公路和铁路交通、土木工程和航空航天工程等多个工业部门广泛应用的重要一步。由此带来的英国先进设计能力的提高将极大地帮助高端制造业保持其竞争优势。
