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．
