摘要
针对飞轮振动测量中转接支架引起的振动数据偏差问题,提出了一种消除转接支架影响的飞轮振动数据处理方法,并进行了实际应用,利用相干函数检验了转接支架频响函数的实际测试精度,实际应用表明该方法具有一定的可行性和有效性.
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.
