摘  要

    磁流变液是可磁极化的固体微颗粒在基液中形成的悬浮液，其流变特性可由外加磁场连续控制。当不加磁场时，磁流变液表现出类似牛顿流体的行为；当外加磁场时，磁流变液中的磁性颗粒沿磁场方向排成链状，这些链状结构阻止了液体的流动，因而改变了磁流变液的流变特性，其流动表现出Bingham塑性体行为，具有粘性和塑性特性。
随着磁流变液在机械应用中的不断发展，越来越多的将磁流变液运用于各种机械器件中。磁流变液在外加磁场增强的过程中，液体的粘度随之增大并最终失去流动性变为固态，此过程耗能小、可逆、能产生较大屈服应力且在豪秒级内完成。利用此一系列性能，在充分考虑磁场、温度、颗粒尺寸、壁面效应和体积浓度等诸因素对应用器件影响的基础上，可开发各种磁流变阻尼器件。由于磁流变液相变的过程在毫秒量级内完成，因此可以做成敏捷度极高的控制元件，用于联接和传递两部件之间的力或力矩。如汽车用离合器、制动器等。磁流变液动压轴承也是基于这个原理设计的。

Abstract

    Magnetorheological fluid is a magnetic pole of the solid particles in suspension, formed in the base of its rheological properties can be made of continuous control plus a magnetic field. When without magnetic field, the magnetic rheological fluid showed similar behavior of Newtonian fluid; When applied magnetic field, the magnetic particles of magnetorheological fluid along the magnetic field direction in chain, the chain structure to prevent the flow of the liquid, and thus change the rheological properties of MRF, the flow show the Bingham plastic body behavior, viscous and plastic characteristics.
    As the MRF in mechanical applications development, more and more application of MRF to various kinds of mechanical device. Magnetorheological fluid in the process of plus enhanced magnetic field, the liquid viscosity increase and eventually lose liquid into a solid, the process energy consumption of small, reversible, can produce a large yield stress and in house finish in second grade. Using this series of performance, in full consideration magnetic field, temperature, particle size, surface effect and volume concentration, etc. Various factors influence, on the basis of the application components can develop all kinds of magnetorheological damping devices. Due to magnetic rheological liquid phase change is accomplished within millisecond level, so you can make it high agility control element, is used to join and transfer force or moment between the two parts. Such as automotive clutch, brake, etc. Magnetorheological fluid dynamic pressure bearing is designed based on this principle.
