Investigation of Averaging Effect on Rotor Rotating Error Measurement

Li Yan Wang Kai Li Qi Xi ChangqingXi'an University of Technology,Xi'an,710049  
The eddy current displacement sensor's averaging effect had been investigated.It indicates that rotor's detailed outline can be averaged,but it has no influences on rotating error measurement.The frequency spectrum of averaging effect had been also deduced.Based on the frequency spectrum,the distortion of sampling data occurred in high frequency region was studied carefully.The paper also provides a theoretical direction in subsequent data processing.
