摘要

本文采用经典统计能量法和修正的统计能量法，在11kW三相感应电机定子上开展了内损耗因子和耦合损耗因子的实验研究。结果表明电机复杂机械结构存在强耦合、非保守、间接耦合的振动传递特点。通过对比两种方法建立的统计能量模型振动预报结果和实验测试结果，验证了两种方法在弱耦合前提下，预报直接耦合振动传递的准确性。在考虑了间接耦合损耗因子后，修正的统计能量法能够极大提高间接耦合的振动预报精度，但在物理相连的强耦合振动传递方面，受限于结构刚度大、模态密度低的特点，两种方法预测振动响应偏低。此外，本文还采用商业软件VA One进行了有限元和统计能量法混合建模，预报的结构响应与实验结果吻合较好，进一步丰富了统计能量法在电机中高频振动建模方面的应用。

Abstract

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.
