摘　　要：为阐明电控增压泵高速电磁阀关键参数间交互作用对电磁阀电磁力的影响机理,首先有效进行超高压共轨系统电控增压泵高速电磁阀参数设计及优化匹配,建立了电控增压泵高速电磁阀三维有限元仿真模型,并通过试验验证了该模型的计算精度;然后,采用响应面法构建电磁力近似模型,并进行了电控增压泵高速电磁阀关键参数交互作用数值计算分析,结果表明,驱动电流与衔铁厚度、衔铁厚度与主磁极半径、主磁极半径与阻尼孔半径这些交互参数对电磁力的影响较大;最后,给出了驱动电流、衔铁厚度与主磁极半径的设计依据,以及主磁极半径和阻尼孔半径优化匹配值。Aiming to reveal the interaction mechanism of key parameters of the high speed solenoid valve of the electric-controlled booster pump,for the better design and optimization matching of the parameters,the three-dimensional finite element simulation model of the high speed solenoid valve for the electric-controlled booster pump was established and verified by experiments firstly.And then the electromagnetic force prediction model was established by using the response surface method,and the interaction of the key parameters was numerically calculated and analyzed by the model.The results indicate that the interaction factors such as driving current with armature thickness,armature thickness with main magnetic pole′s radius,and main magnetic pole′s radius with damping hole′s radius have great influence on the electromagnetic force.The design basis of the driving current,armature thickness and main magnetic pole′s radius were presented together with the optimal matching value of main magnetic pole′s radius with damping hole′s radius.
