随着人类研究活动向着更微观尺度发展，微振动隔振技术因此愈发重要。磁流变技术的研究长期以来主要针对宏观尺度载荷下的振动问题。磁流变材料在微振动下表现出与宏观尺度载荷下不同的非线性特性。微振动下的磁流变材料的力学特性是发展磁流变微振动隔振技术的前题和基础。本项目基于自主研制的磁流变液变刚度隔振技术和多层磁流变弹性体隔振技术，提出了一种变刚度变阻尼的磁流变微振动隔振技术。本项目将系统地研究磁流变材料在不同载荷下的非线性力学特性，研究颗粒与基体/基液，基体/基液与金属壁界面之间的相互作用，探索磁流变材料在微振动作用下产生非线性力学性能的机理及内部相互作用本质，建立能正确描述微振动磁流变材料力学性能的力磁耦合非线性力学模型，为这种智能材料的发展及其在微振动领域的应用提供理论和实验依据。

With the development of micro scale investigations, the isolation of micro vibrations is more and more important. The investigations of magnetorheological(MR) technologies focus on the objectives in macro scale. The MR materials exhibit the interesting nonlinear properties under micro vibrations. Thus the mechanics properties of MR materials is the prime investigation for the development of MR micro vibration technologies. This project proposed a MR micro vibration isolation technology on the basis of variable stiffness MR fluid isolation and multilayer MR elastomer isolation. This project plans to systematically investigate the mechanics properties of MR materials subjected to different loadings. And it also plans to investigate the effects of interfaces between particles and matrix, as well as between the matrix and boundaries. This project also plans to establish a force-magnetic model to predict the nonlinear performance of MR materials subjected to micro vibrations, which provide the experimental and theoretical support for the development of MR materials and the application on micro vibration isolation technology.
