摘　　要：根据磁流变液的可控流变特性设计了一种双线圈磁流变阀,阐述了双线圈磁流变阀的工作原理,并对其进行了压降分析。利用ANSYS软件对双线圈磁流变阀进行磁场仿真,研究了两个线圈的通电方向、阀芯倒角和工作间隙宽度对阻尼间隙中间的磁感应强度和压降的影响,依据对各种结构参数的研究结果得出双线圈磁流变阀的最终结构尺寸,并加工出双线圈磁流变阀。相关结论和方法对磁流变阀的结构设计具有一定的指导意义。A double-coil magnetorheological （MR） valve was designed according to the controllable rheological properties of the magnetorheological fluid. The working principle was introduced, and the pressure drop was also discussed. The magnetic field simulation was conducted using ANSYS software ; the effects of the current directions of the double-coil, the valve spool chamfer and the width of the resistance gap on the magnetic induction intensity of the resistance gap and the pressure drop were also investigated. Finally, the optimal structure parameters of the double-coil valve were achieved, and the prototype was also manufactured. The relevant results can provide some guide for the design of other types of MR valve.
