Abstract:Aimingattheshortcomingsintraditionalrollingbearingfaultsignalfeatureextraction,arollingbearingfault diagnosismethodbasedonConvolutionalBlockAtentionModule(CBAM)andresidualnetwork(ResNet5O)isproposed.Thefault signalsintheCaseWesternReserveUniversitydatasetwererandomlyandlocalloverlappedsampled,andthebearingfault signalswereconvertedintotwo-dimensionaltime-frequencydomainimagesusingICEEMDANandHilbert.Thetime-frequency domainimagesweretheninputintotheResNet5O-CBAMnetworkmodel.,trainingandtestingtheaccuracyofthemodel. Convolutionalneuralnetworksandtransferlearningareaddedtothenetworkmodeltosolvetheproblemsofdificultyindata acquisitionandlongtraining time.ExperimentshaveprovedthatResNet5O-CBAMhasstrong faultfeatureextractioncapablities. Compared with other network models,the accuracy rate is 8%~15% higher. Finally,rolling bearing signals are collected on a servosystemexperimentalsimulationplatform,andtheimprovednetworkmodelisusedfordiagnosis.Theresultsprovethatthis diagnosis method has high accuracy in rolling bearing fault diagnosis.
