摘要: 以电磁理论为基础,建立阻尼连续可调 ( CDC) 减振器先导阀电磁场和电磁力 数学模型,基于磁路分析选用合适的先导阀材料,通过仿真得到先导阀的磁场分布情 况,验证材料选用的合理性。仿真分析各个结构参数对电磁力的影响规律,利用方差分 析法获得对电磁力影响较大的先导阀结构参数,进一步利用正交试验法针对所选取的参 数进行协同优化,获得优化参数组合方案。结果表明,当 D2 = 12. 6 mm、δ4 = 0. 25 mm、 L2 = 4 mm 时,电磁铁具有较优的恒力特性。

Abstract: The mathematical model of electromagnetic field and electromagnetic force of the continuous damping control shock absorber’s pilot valve was established on the basis of electromagnetic theory. The appropriate pilot valve material was selected based on the magnetic circuit analysis,and the rationality of the material selection was verified by the magnetic field distribution of the pilot valve which was obtained through simulation. The influence of various structural parameters on the electromagnetic force was analyzed by simulation,and the structural parameters of the pilot valve with greater influence on electromagnetic force were obtained by variance analysis method. Furthermore,the optimized parameter combination scheme was obtained through collaborative optimization for the selected parameters which was carried out with the orthogonal experiment method. The results show that the electromagnet has better constant force characteristics when D2 = 12. 6 mm,δ4 = 0. 25 mm,L2 = 4 mm.

Key words: CDC shock absorber, pilot valve, electromagnet, cooperative optimization, orthogonal test
