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.

该项目旨在提高对磁化固体颗粒和流体在导管中的衰减特征的理解，但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在地震条件下的大规模磁性阻尼器的设计中起着重要作用。这些阻尼器促进了对历史结构的保护，并消除了建筑结构的昂贵重建。该项目计划进行实验性和数值研究，以开发可靠和准确的预测模型，以提高对下一代磁性磁性阻尼器的地震衰减的理解，在半活性控制设备中普遍存在，以及此类设备抑制升高结构振动的能力。
