摘要: 针对外置电磁阀用比例电磁铁恒力特性要求,在Maxwell软件2D模块中建立了比例电磁铁参数化模型。通过比例电磁铁实验台验证了仿真的正确性,根据仿真结果验证材料及磁路分割法使用的正确性,并确定了衔铁工作行程。在此基础上使用单因素参数分析法,分别对结构参数隔磁环高度L2、径向间隙δ4、限位片直径D0和径向间隙δ2在衔铁工作行程内的变化对电磁铁恒力特性的影响情况进行了分析,并根据分析结果利用正交试验法对所选用参数进行优化分析,获得较优的参数组合。仿真表明,当L2=4.1 mm、δ4=0.30 mm和δ2=0.05 mm时比例电磁铁有较优的恒力特性,通过仿真验证该最优组合参数,电磁力方差值相比原结构下降了12.96 %,恒力特性得到明显提高。

Abstract: Aiming at the requirement of constant force characteristics of proportional electromagnet for external solenoid valve,a parametric model of proportional electromagnet was established in the 2D module of Maxwell software. The correctness of the simulation was verified by the proportional electromagnet test bench. The correctness of the material and the magnetic circuit segmentation method was verified from the simulation results and the armature working stroke was determined. On this basis,the single factor parameter analysis method was used to analyze the influence of the structural parameters of the magnetic isolation ring height L2,the radial clearance δ4,the diameter of the limit piece D0 and the radial clearance δ2 on the constant force characteristics of the electromagnet in the working stroke of the armature. According to the analysis results,the orthogonal test method was used to optimize the selected parameters to obtain a better parameter combination. The simulation shows that the proportional electromagnet has better constant force characteristics when L2 =4.1 mm,δ4 = 0.30 mm,and δ2 =0.05 mm. The optimal combination parameters are verified by simulation. The electromagnetic force variance is 12.96 % lower than the original structure,and the constant force characteristics are significantly improved.

Key words: electromagnetic force, proportional electromagnet, orthogonal test, optimization analysis
