磁流变液机理及行为描述的理论研究现状

Research Status of Mechanism and Behavior Description of Magnetorheological Fluids

概述了解释磁流变液链化机理的3种理论即磁畴理论、相变理论和偶极矩理论,以及链化机理的定量分析和数值模拟。同时介绍了3种描述磁流变液行为的理论方法和途径即宏观本构描述、微观分析描述和数值模拟描述。上述磁流变液的基础理论研究对优化磁流变材料的配置和设计高性能磁流变装置具有重要意义。

Three theoretical explanations, including magnetic domain theory, phase transition theory and dipole theory, are introduced for the mechanism of chain-formation in magnetorheological fluids under external magnetic field. The quantitative analysis for chain-formation are presented. Three ways to describe the property and behavior of magnetorheologieal fluids, including constitutive model, micro-analysis and numerical simulation, are summarized.
