【摘要】 提出一种基于解析计算方法的磁浮列车空气隙磁通密度的计算方法。首先对磁浮列车定子、动子电流层密度进行傅里叶级数展开,然后借助谐波分析方法,计算出磁浮列车悬浮气隙中的磁通密度。解析方法的结果与ANSYS模型分析的空气隙磁通密度相比较,证实了解析分析和模型分析的一致性和所采用的解析计算方法的正确性和有效性。此方法为进一步建立磁浮列车的实时运动控制模型提供了基础。更多还原

【Abstract】 Levitation airgap is not constant because of incontinuous distribution of the stator and mover, so a method based on analytical computation is introduced. Current density of the stator current sheet and mover current sheet of the TR08 Maglev vehicle are both expanded by Fourier series. Then, it can compute the flux density distribution in the air-gap between the stator and mover. The result of the analytical model and that of ANSYS model prove that the method of analytical computation is consistent with that of ANSYS, and the method of analytical computation is correct and valid. The conclusion that generator boarded on Maglev vehicle works with 5th and 7th harmonic wave of the magnetic field is also derived.更多还原
