低速磁浮列车曲线通过时电磁铁动态导向力分析

导向力的大小与低速磁浮列车的曲线通过能力密切相关,磁浮列车运行过程中,悬浮电磁铁要发生横移、摇头等运动,从而影响导向力的大小。文章以一电磁型低速磁浮列车的悬浮电磁铁为研究对象,首先推导出了悬浮电磁铁在曲线上的横向平衡位置,然后通过几何分析得出了电磁铁导向力与横向偏移量、摇头角以及两者同时存在情况下的动态变化关系,这些分析结果为以后的相关研究奠定了基础。

Analysis on magnet dynamic guidance force when low-speed maglev train passing curve

The value of guidance force has an important relation with the curving performance of the low-speed maglev train. The suspension magnet will occurs horizontal motion and yaw motion when maglev train running, then affects the value of guidance force. This paper takes the suspension magnet of an EMS low-speed maglev train as the research object. It derives out its lateral equilibrium position at first. Then through geometry analysis, it obtains the change relation of the guidance force with the displacement, yaw as well as both occurs at the same time. These analysis results have laid on an important foundation for the later further research.
