利用磁流变液体的可控特性，设计了一种外侧圆环阻尼间隙双线圈磁流变阀，同时计算了双线圈磁流变阀的磁路。采用ANSYS有限元仿真软件对双线圈磁流变阀进行了建模仿真分析，比较了绕线筒直径、有效阻尼长度及阻尼间隙对磁场特性的影响，得出了最佳磁力线分布和磁感应强度大小。建立了双线圈磁流变阀的压差数学模型，分析了磁流变阀结构参数对压降特性的影响。相关结论的应用可有效地提高阀的工作效率。

In this paper,a double coil magnetorheological (MR)valve with outer annular resist-ance gap was developed according to the rheological properties of magnetorheological fluids. Meanwhile,the magnetic circuit of the double coil MR valve was also calculated.The finite ele-ment modeling and analysis of double coil MR valve were carried out using ANSYS,the effects of bobbin diameter,active core length and thickness of resistance gap on the magnetic flux density were investigated too,and the optimal magnetic field distribution and magnetic flux density of the double coil MR valve were achieved.The mathematical model of the pressure drop of the double coil MR valve was established,and the influences of the structure parameters of the double coil MR valve on the pressure drop were obtained.The new valve design can improve the efficiency of double coil MR valve significantly.
