Multi-faults Diagnosis Method for Gearboxes Based on SWD-AVDIF
摘要
Abstract
The problem of multi-fault diagnosis of gearboxes under the condition of noise interference and uneven distribution of fault intensity is studied. A fault diagnosis method based on Swarm Decomposition and Average Difference Filter (SWD-AVDIF) is proposed. Firstly, Swarm Decomposition (SWD) is used to decompose the vibration signal into several Oscillatory Components (OCs). Then, the OCs are demodulated into SWD-AVDIF spectrum with AVDIF operator to realize accurate diagnosis.Compared with EMD, the analysis results with simulation signal verify the superiority of SWD method in frequency discrimination ability. The method is applied to the mechanical multi-fault signal analysis. The results show that this method can effectively decompose different fault signals and strengthen fault features. This study provides a new method for multi-fault diagnosis of gearboxes.关键词
