单磁铁的静态磁场和悬浮力分析

Analysis of magnetic field and levitation force of single magnet

以上海TR高速磁悬浮列车为分析对象,用ANSYS软件建立单磁铁模型,对其额定工况进行了静态磁场分析,着重分析了励磁电流和气隙高度的变化对悬浮力的影响,为悬浮电磁铁优化设计和磁浮列车的静止悬浮稳定性控制提供了依据。最后,通过电磁铁组合模型的静态磁场分析,证明了单磁铁分析结果的准确性。

Through building single magnet model with ANSYS, according to the high-speed maglev vehicle in Shanghai, the magnetic field distribution under standard working conditions and that how the design parameters changing affected the levitation force were analyzed, The academic basis for optimal design of magnet and stability of levitation control were offered. Finally, by the anegsis of the combining magnets model, the accuracy of the analysis of the single magnet model was proved.
