Seismic attenuation of structures through use of magnetorheological dampers

该项目旨在提高对磁化固体颗粒和流体在管道中共同流动的衰减特性的理解，该管道受到快速地面运动产生的地震波的影响。流体中磁化固体颗粒的分布对大规模磁流变阻尼器的抗震设计起着重要的作用。这些阻尼器促进了对历史建筑的保护，并消除了昂贵的建筑结构重建。该项目计划进行实验和数值研究，以开发强大而准确的预测模型，以提高对下一代磁流变阻尼器地震衰减的理解，这种阻尼器在半主动控制设备中很普遍，以及这种设备抑制结构振动的能力。

This project aims to improve understanding of the attenuating characteristics of the co-flowing of magnetised solid particles and fluid in a conduit subject to seismic waves generated by rapid ground movement. The distribution of magnetised solid particles in fluid plays an important role in the design of large-scale magnetorhelogical dampers for seismic conditions. These dampers promote the protection of historical structures and eliminate costly rebuilding of architectural structures. The project plans to perform experimental and numerical investigations to develop robust and accurate predictive models to improve understanding of the seismic attenuation of next-generation magnetorhelogical dampers, prevalent in semi-active control devices, and of the ability of such devices to suppress elevated structural vibrations.
