摘要: 为实现永磁同步电机噪声的精确预测与实验对标,本文提出一种与标准化实验测量规程高度一致的六面体声学有限元仿真方法。 以一台 10 极 12 槽永磁同步电机为研究对象,通过建立电磁-结构-声学多物理场耦合模型,计算电磁力并获取机壳振动响应,进而采用 6 面体响应面的声学有限元法计算声辐射,并通过标准化噪声测试对该方法进行了验证。 结果表明,仿真与实验测得的总声压级分别为 35. 42 dB 与 32. 7 dB,相对误差为 8. 32%,且二者频谱分布特征高度一致,该误差在工程可接受范围内。 有效验证了所提仿真方法在电机噪声预测中的准确性与工程实用价值,为仿真与实验的系统对标提供了有效方法。

Abstract: To achieve accurate prediction and experimental validation of noise in permanent magnet synchronous motors,a hexahedral acoustic finite element simulation method that is highly consistent with standardized experimental measurement procedures is proposed in this paper. A 10-pole 12-slot permanent magnet synchronous motor is taken as the study object. By establishing an electromagnetic-structural -acoustic multiphysics coupling model,the electromagnetic forces are calculated and the vibration response of the motor housing is obtained. Subsequently,the acoustic radiation is calculated using the acoustic finite element method with a hexahedral response surface. The proposed method is verified through standardized noise tests. The results show that the overall sound pressure levels obtained from simulation and experiment are 35. 42 dB and 32. 7 dB, respectively, with a relative error of 8. 32%. Furthermore, spectral distribution characteristics are highly consistent. This error is within the acceptable range in engineering, which effectively verifies the accuracy and practical value of the proposed simulation method for motor noise prediction. An effective solution is provided for the systematic alignment between simulation and standardized experimental measurements.
