摘　　要：阐述了磁流变流体的磁流变特性及其Bingham模型,依据磁流变流体在磁场作用下的可逆、可控特性设计了磁流变阀。采用ANSYS有限元分析软件对设计的磁流变阀3种结构模型进行了磁场分析。研究磁流变阀的结构与磁流变流体的磁感应强度和磁流变阀性能的关系。分析结果表明:根据磁力线分布和磁感应强度大小合理设计磁流变阀结构,可使磁流变流体在相同外加电流条件下获得更高磁感应强度,提高磁流变阀的性能。The magnetorheological features and Bingham model of magnetorheological fluid are elaborated,and a magnetorheological valve is designed on the basis of the reversible and controllable characteristics of magnetorheological fluid.Then three models of magnetorheological valve are analyzed for its magnetic field by ANSYS software.Afterwards the relation between magnetorheological valve structure and magnetic flux density,the performance of magnetorheological valve is studied,which result indicates：reasonable design of the magnetorheological valve in accordance with the distribution of magnetic line and the magnetic induction can obtain higher magnetic induction intensity and enhance the performance of magnetorheological valve at the same current intensity.
