摘要
针对中低速磁悬浮列车中永磁与电磁混合悬浮磁铁存在的吸死问题,研究了一种基于不等宽结构的混合悬浮装置。分析该装置中U型铁、F型轨及两者间气隙的电磁关系,建立基于不等宽结构悬浮装置的模型。以株洲中低速磁浮商业试验线列车为基础,使用ANSOFT软件进行仿真,对该悬浮装置进行了设计及验证。仿真结果表明:在改进的不等宽混合悬浮装置中,无论气隙间距大小如何,该不等宽结构中的悬浮力始终与重力保持平衡,可实现列车悬浮的"0功率"控制。
A kind of hybrid suspension system with the electro and permanent magnets based on unequal width structure was studied to solve the problem of the suspension contact existed in medium-speed maglev trains, By analyzing the electromotive relationship of the U-shaped iron, F-shaped rail and air gap using ANSOFT, the model of a suspension system based on the unequal width structure was established. The suspension system was designed and verified on the basis of Zhuzhou maglev test line. Simulation results showed that regardless of the size of air gap in the new suspension system, the attraction force between the iron and rail always could balance the gravitational three, thereby making zero power control possiblc.
