Magnetorheological elastomer (MRE) is one of the smart materials whose stiffness and damping ratios can be controlled by applying a magnetic field. Several studies have been conducted on the utilization of MREs as base isolators in semi-active systems. A base isolator using a MRE utilizes an electromagnetic system to generate a magnetic field for the MRE. Generally, single-layered electromagnetic systems are used in MRE-based isolators. The single-layered electromagnetic system forms an inter-space between the MRE and the electromagnetic system to consider the deformation of the MRE. A larger inter-space is observed when the strain of the MRE is increased, which causes limitations owing to the excessive volume and electric power of the base isolator. Therefore, a electromagnetic system is proposed to overcome these limitations, in which the single-layered electromagnetic system is divided into several layers and behaves according to the deformation of the MRE. To validate the su...

使用磁流变弹性体改进基础隔离器的多层电磁系统的开发

磁流变弹性体（MRE）是一种智能材料，其硬度和阻尼比可以通过施加磁场来控制。关于在半主动系统中利用MRE作为基础隔离器的研究已经进行了几项。使用MRE的基本隔离器利用电磁系统为MRE产生磁场。通常，在基于MRE的隔离器中使用单层电磁系统。单层电磁系统在MRE和电磁系统之间形成一个空间，以考虑MRE的变形。当MRE的应变增加时，会观察到较大的间隙，这会由于基本隔离器的体积和功率过大而造成限制。因此，提出了一种电磁系统来克服这些限制，其中，单层电磁系统分为几层，并根据MRE的变形而运行。为了验证su ...
