摘　　要：气动控制阀因其结构简单、成本低等优点,在航空航天领域中具有重要应用。为了研究气动控制阀中异性隔磁机构最优位置,介绍了液体导弹发动机油箱用电磁阀的结构及工作原理,利用电磁场有限元分析软件Maxwell建立电磁阀二维仿真模型,对电磁阀中一体化异型隔磁结构在不同位置的模型进行了仿真计算,得到了衔铁在全行程下的电磁力特性曲线。通过曲线可以看到此异性隔磁机构在线圈中间偏下一点的位置时,受到的电磁力随着阀芯开度的变化较为稳定,且线圈受到的电流激励越大,衔铁所受电磁力越大。搭建了试验平台,进一步验证了仿真分析的准确性,研究结论可为气动控制阀的设计提供参考。Pneumatic control valves have important applications in the aerospace field because of their simple structure and low cost.In order to study the optimal position of the anisotropic magnetic isolation mechanism in the pneumatic control valve,the structure and working principle of the solenoid valve for the fuel tank of the liquid missile engine are introduced,and the two-dimensional simulation model of the solenoid valve is established using the electromagnetic field finite element analysis software Maxwell,and the model of the integrated anisotropic magnetic isolation structure in the solenoid valve at different positions is simulated and calculated,and the electromagnetic force characteristic curve of the armature at full stroke is obtained.Through the curve,we can see that this heterogeneous magnetic isolation mechanism in the middle of the coil at the lower position,the electromagnetic force is more stable with the change of the spool opening,and the greater the current excitation of the coil,the greater the electromagnetic force on the armature,which provides a design reference for the design of pneumatic control valves.
