摘要：为分析SRM在工作过程中的电磁振动与噪声，本文采用三维多物理场有限元模型, 建立了SRM耦合的电磁机械声场模型。通过对SRM电磁场进行瞬态分析，得到径向电磁力，分析了定子模态和固有频率以及电磁力耦合作用下定子的振动响应。最后通过边界元法对SRM的声学模型进行了噪声预测。

Abstract: In order to analyze the electromagnetic vibration and noise of SRM,a threedimensional multi physical field finite element model was adopted and a SRM coupled electromagnetic mechanical sound field model was established. Radial electromagnetic force was obtained by transient analysis of SRM electromagnetic field, and the vibration response of stator was analyzed by the stator mode and natural frequency as well as the electromagnetic force. Finally, the acoustic model of SRM was predicted by the boundary element method.
