英文摘要：

Aiming at the problem that the traditional morphology filter and wavelet de-noising algorithms cannot very well reduce the noise of rotor bearing load signal, a new wavelet morphology filter method was proposed in this paper. The methods of wavelet morphology filter and the generalized morphology filtering were used to simulation and experiment signals, respectively, and the results of the two methods were compared. It was demonstrated that the wavelet morphology filter method could depress the random signal more effectively, and it also can improve the SNR （ signal-noise ratio）. In addition, this new method can inhibit the de-noising signal distortion and accomplish the processing of the signal de-noising.
