| 摘 要： | 本文提出了有限元和傅里叶级数分析相结合的方法来计算电机辐射的声功率,该电机具有轴对称外形,计算值与实验结果相吻合证明此法的有效性,它考虑了端盖对辐射功率的影响,这在现有的其他方法中是不可能做到的。

| Abstract: | This paper presents a technique, whih combines finite element and Fourier series analysis to calculate the acoustic power radiated from an axi symmetric electrical machine, for which predictions are validated against measurements on a 3-phase induction motor. The technique is capable of accounting for the effect of end-shields on the sound radiation, which would not be possible with existing analytical methods. |
