摘　　要：以高温气冷堆中氦气透平转子的试验模型为研究对象,利用电磁轴承不接触的电磁力实现对转子支承和激励的性质,采用正弦扫频的方式获得高温气冷堆氦气透平转子试验模型转子的频域的分析数据,然后利用模态分析理论获得转子的传递函数和模态振型。从试验结果可以看出,获得的传递函数和模态振型不但验证了理论分析的结果,而且为控制器设计和系统故障检测提供了必要的分析依据。Because active magnetic bearing could support and inspire the rotor with contactless electromagnetic force, some data in the frequency domain are acquired when the inspired sinusoid sweeping frequency signals are input into the rig, which is an experiment model of the helium turbine rotor in the hightemperature air-cooled reactor （HTR）. With the method of modal analysis, the transfer function and modal shapes are drawn. These results not only could verify the theoretic analysis result, but also could be provided for the controller design and system failure diagnosis.
