摘要为了分析车用爪极发电机的固有特性，对爪极发电机进行了模态试验和有限元分析。首先对发电机定子铁芯和定子总成进行模态试验，获取了其模态振型和模态频率。根据定子铁芯与绕组的有限元等效模型和获取的模态参数，识别出铁芯和绕组的等效各向异性材料参数。其次考虑各零部件之间复杂的连接关系，建立了发电机整机的自由模态有限元模型，自由模态试验表明该模型具有较高的准确性。最后在自由模态模型的基础上建立了发电机约束模态有限元模型，并进行了振动试验。自由模态试验和振动测试结果表明，综合考虑定子铁芯和绕组的各向异性材料特性和螺栓预紧力等因素能够准确预测爪极发电机的模态特性，为爪极发电机振动与噪声的数值预测和减振降噪研究奠定了基础。

Abstract：

To analysis the inherent characteristics, finite element (FE) and experimental modal analysis was conducted for a claw-pole alternator. Firstly, modal shapes and frequency were obtained through modal test for stator, and orthotropic material parameters of stator core and windings were then identified according to finite element equivalent model and test results. Secondly, FE model of free modal was built considering the complex connection between different components, and its accuracy was validated through free modal test. Finally, Constrained FE model was built on the basis of free modal and vibration test was conducted. The results of free modal test and vibration test reveal that modal characteristics can be precisely predicted through proposed model synthesizing orthotropic material parameters and bolt pretension, and it lays the foundation for prediction and reduction of vibration and noise.

Key words： claw-pole alternator modal analysis orthotropic bolt pretension vibration
