摘　　要：发电机是风机系统的核心部件,其动力学性能关系到整个系统的可靠运行。本文采用正交各向异性材料来简化定子和转子的复杂铁心结构,大幅减少了单元数目和计算规模。在部件级建模的基础上,建立了发电机的整机动力学模型。利用锤击法进行整机模态实验,并将仿真的固有频率和模态振型与实验结果进行对比,验证了本文模型的有效性。Generator is the core component of fan system and its dynamic performance is related to the reliable operation of the whole system.Orthotropic materials are used to simplify the complex core structure of stator and rotor in this paper,so that the number of elements and calculation scale are greatly reduced.Based on component-level modeling,the dynamic model of generator has been established.The validity of the model in this paper has been verified by using hammering method in the modal experiment of the whole machine and comparing the inherent frequencies and modal shapes with experimental results.
