摘要
电流变体是具有高介电常数的固体微粒分散于低介电常数的绝缘液体中所形成的一类稳定胶状悬浮液。这类悬浮液在外加电场的作用下 ,具有在液体和固体之间进行快速可逆转变的特性 ,因此成为一类发展较快的智能材料 ,在汽车、通用机械及机电一体化等领域有着广泛的应用前景。本文概述了电流变现象、电流变体的工作机理及材料的研究近况 ,并介绍了电流变体的工程应用现状 。
The electrorheological materials are stable suspensions consisting of fine particles of high dielectric constant in a low dielectric constant carrying fluid. When applying high electric fields on the electrorheological meaterial, it represents a rapid and reversible change between liquid and solid states. As a kind of novel smart material, the electroheological material will be probably and widely used in the fields of electromechanical control, automobile and other general machinery. In this article, the latest research progress on the electrorheological behavior, mechanism of electrorheological materials is summarized and the application of electrorheological materials in the engineering fields is presented Meanwhile, the problems to be solved in this research field are also stated.
