| Abstract: | Waveform distortion of super low frequency standard shaker is an important factor which influences the calibration precision.A precept of distortion control which uses harmonic notch feedback method is discussed in this paper.The control process is analyzed,and the feed-back arithmetic is given.Experiment shows that the method can rapidly reduce the distortion of vibration table,and the distortion could be con-trolled in the range of 2%. |
