摘要：

高速电磁阀性能直接影响高压共轨柴油机燃油喷射系统的特性，为揭示新型高速电磁阀串并联永磁与电磁混合励磁的作用机理，采用数值模拟方法分析了串、并联永磁体对系统电磁力的影响。首先采用ANSYS Maxwell软件建立了新型高速电磁阀仿真模型并验证了模型的精度；然后通过仿真分析了全工况下串、并联永磁环参数及其交互作用对高速电磁阀电磁力的影响。结果表明：电磁力与并联永磁环高度正相关，而与串联永磁环高度负相关；随着驱动电流的增加，串联永磁环高度与并联永磁环高度之间的交互作用逐步减弱。

Abstract:

The performance of high?speed solenoid valve directly affects the characteristics of fuel injection system in high pressure common rail diesel engine. In order to reveal the hybrid excitation mechanism of series and parallel permanent magnet with electromagnetism for the novel high?speed solenoid valve， the effects of series and parallel permanent magnet on the electromagnetic force of the system are analyzed by numerical simulation. Firstly， the simulation model of novel high?speed solenoid valve is established by using ANSYS Maxwell software with its accuracy verified. Then， a simulation is conducted to analyze the effects of series and parallel permanent magnet rings and their interaction on the electromagnetic force of high?speed solenoid valve in full working condition. The results show that the electromagnetic force is positively correlated with the height of parallel permanent magnet ring， and is negatively correlated with the height of series permanent magnet ring. With the increase of driving current， the interaction between the height of series permanent magnet ring and the height of parallel permanent magnet ring gradually weakens.

Key words: high pressure common rail diesel engine, novel high?speed solenoid valve, electromagnetic force, series and parallel permanent magnet, interaction
