Hydraulic pump vibration signal preprocessing is the basis for failure prediction. The vibration signal preprocessing method based on ILCD fusion is proposed to solve the problem that the vibration signal is nonlinear and the feature information is weak. Firstly, the high-frequency harmonics are combined with ILCD to decompose multi-channel vibration signals, and ISC components can be achieved. Secondly, the sensitive factors are defined as evaluation indexes, and the sensitive components containing the fault feature information are screened and weighted fusion. The reconstructed signal is obtained to reduce the noise and other interference components and effectively extract the fault feature information. Finally, the effectiveness of this method is verified by measuring the vibration signal of the hydraulic pump.
