摘　　要：为了比较螺线管式静铁芯电磁阀与极柱式静铁芯电磁阀产生的静态电磁力的大小与适用场景,首先建立了两种静铁芯的有限元模型,并通过实验进行了模型的验证;然后对比了两种结构在不同电流、不同气隙下的静态电磁力及静铁芯散热情况。由仿真结果得出,在同等外形体积下,螺线管式静铁芯电磁阀随着线圈电流的增加电磁力稳步增大,但电流过大时线圈温度过高,电流40 A工况下线圈温度达186.2℃,适用于小电流小行程的工作环境;而极柱式静铁芯电磁阀随着线圈的电流增加电磁力上升的速率更快,电磁力也更大,裸露的单层线圈保证了散热,电流40 A工况下温度仅为51.1℃,适用于大电流大行程的工作环境。同时极柱式静铁芯电磁阀电磁力随着极柱数的增加先增大后减小。同等条件下,六级柱式静铁芯电磁阀产生的电磁力最大。可为新品高速电磁阀静铁芯的设计提供理论指导。In order to compare the applicable scenes and the magnitude of static solenoid force generated by solenoid static iron core solenoid valve and pole static iron core solenoid valve.Firstly,the finite element model of the two types of static iron cores is established and the model is verified through experiments,and then the static solenoid force of the two types of structures is compared in different currents and under different air gaps.Through the calculation and analysis,it is concluded that in the same shape and volume,solenoid force generated by solenoidal static iron core steadily increases with the increase of coil current.Because the coil temperature is too high when the current is too high,under the working condition of 40 A current,the coil temperature reaches 186.2℃.It is suitable for small current and small stroke working situation.While the solenoid force generated by the pole static iron core solenoid valve rises faster and is also larger with the increase of the coil current,and the bare single-layer coil ensures heat dissipation,under the working condition of 40 A current,the temperature is only 51.1℃.It is suitable for large current and large stroke working situation.Meanwhile,the pole static iron core solenoid valve solenoid force increases first and then decreases with the increase of the number of poles.Under the same conditions,six-pole static iron core solenoid valve generates the largest solenoid force and it provides theoretical guides for the design of new high-speed solenoid valve static iron core.
