基于双电磁铁结构的新型电磁阀研究

Research on novel solenoid valve based on double solenoid structure

为满足列车对真空制动电磁阀的性能要求,提高电磁阀关闭阶段的灵敏度,提出一种双电磁铁结构电磁阀,采用电磁场有限元软件对其进行建模仿真,并具体分析其结构对静动态情况下电磁场分布及运动规律的影响。结果表明,该种类型电磁阀能有效提高灵敏度,同时也可有效降低电磁力在开闭阶段末期对线架组件的冲击。

In the view of meeting the performance requirements of original vacuum brake solenoid valve for train and improving the sensitivity of the solenoid valve in the closing phase, it introduces the double solenoid valve structure, simulates its electromagnetic field by finite element software, analyzes its static and dynamic performance, explains the reason of the change of the electromagnetic valve＇s magnetic flux density in the opening and closing phases. This new valve structure can reduce the impact at opening and closing phase.
