| Abstract: | A method used to modify the deviation of flywheel vibration measuring data is presented in this paper. Frequency response function （FRF）,used to describe the frequency response characteristics of fixture in vibration testing system is analyzed. An approach for measuring effective FRF,then a formula used to modify vibration data is then developed and determined. By coherence function,accuracy of the FRF measuring approach is estimated. Experiment results show that the method improves the accuracy of flywheel vibration data. |
