| 摘 要： | 运用经验模态分解法获得一系列表征信号特征时间尺度的固有模态函数IMF,计算各个IMF与原信号之间的灰色关联度,剔除与信号关联度低的IMF,从而达到滤波的目的。通过对仿真信号和泵机组实测信号的诊断,证明了该方法的有效性和可行性。

| Abstract: | A series of intrinsic mode functions（IMF）were obtained of representing the characteristics,time,scale of signals using EMD,the gray relevancy between IMF and original signals was calculated,the IMF with low relevancy to the signals was eliminated,and the filtration was realized.The method was efficient and feasible through diagnosing the simulative signals and measured signals of the pump set. |
