摘要：
Experimental study was carried out on the internal and coupling loss factors of an 11 kW three-phase induction motor stator using the classic statistical energy analysis (SEA) and modified SEA. The results show that strong coupling and indirect coupling exist between the non-conservative motor structure subsystems. By comparing with the experimental vibration response, the predicted results based on the two SEA models have similar precision for direct vibration transmission with weak coupling. The modified SEA model can greatly improve the prediction accuracy by introducing the indirect coupling factor, which is considered to be zero in classic SEA. However, for strong coupled and physically connected subsystems, both methods predict lower vibration response than experiment due to high rigidity and lower mode count. Finally, the FE-SEA hybrid method is used with commercial software VA One, and the simulated vibration has a good agreement with experiment, which expands the application of SEA on the study of motor structures. © 2020, Editorial Office of Journal of Vibration and Shock.
