| 摘 要： | 对涡流式位移传感器测头的均化效应进行了理论分析，指出被测转子的细微轮廓可以被均化，其回转误差的测量不受均化影响。推导了均化效应的幅频特性曲面，根据此幅频特性，对采样数据的高次成分的失真现象进行了深入分析。

| Abstract: | 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. |
