摘　　要：为深入研究电控增压泵电磁阀电磁力与能耗特性,采用有限元分析方法建立了电控增压泵高速电磁阀的三维静磁场仿真模型,并用试验数据验证了模型的准确性;通过数值仿真分析开展了驱动电流和结构参数(线圈匝数、磁极半径、工作气隙)对电控增压泵电磁阀电磁力与能耗的特性研究,得出各参数对电磁阀电磁力与能耗间的权重影响及量化分析。结果表明:主副磁极半径对电磁力影响占比最大,为38.15%;驱动电流次之,占比为31.08%;线圈匝数对电磁力影响占比为17.06%;工作气隙对电磁力影响占比为13.71%。从能耗角度分析了电控增压泵电磁阀驱动电流、线圈匝数、主副磁极半径和工作气隙的占比,其中线圈匝数能耗占比最大,为54.85%;驱动电流次之,为44.99%;主副磁极半径和工作气隙能耗占比最小,仅有0.16%。In order to further study the electromagnetic force and energy consumption characteristics of the solenoid valve of the electronic-controlled booster pump, a 3D static magnetic field simulation model of the high-speed solenoid valve of the electronic-controlled booster pump was established by using the finite element method, and the accuracy of the model was verified by the experimental data. Through numerical simulation analysis, the characteristics of the electromagnetic force and power loss of the solenoid valve of the electric-controlled booster pump were studied by driving current and structural parameters(the number of coil turns, magnetic pole′s radius, working air gap), and the weight influence of each parameter on the electromagnetic force and power loss of the solenoid valve was obtained and the quantitative analysis was made. The results show that the influence of the radius of major and vice magnetic poles on electromagnetic force accounts for 38.15%, followed by the driving current which accounts for 31.08%, the number of coil turns which accounts for 17.06%, and the working air gap which accounts for 13.71%. From the perspective of power loss, the ratio of driving current, coil turns, radius of major and vice poles and working air gap of electric-controlled booster pump solenoid valve were analyzed. The ratio of coil turns(54.85%) is the highest, followed by the driving current(44.99%), and the minimum ratio of the radius of major and vice magnetic poles and working air gap is only 0.16%.
