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.

该项目旨在提高对管道中磁化固体颗粒和流体在快速地面运动产生的地震波作用下的衰减特性的了解。磁化固体颗粒在流体中的分布对地震条件下的大型磁流变阻尼器的设计具有重要意义。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，以开发稳健和准确的预测模型，以提高对半主动控制设备中流行的下一代磁流变阻尼器的地震衰减以及此类设备抑制升高的结构振动的能力的了解。
