State Research and Application of Multiple-pulse Excitation Method in Diagnosis of Bearing Ball Wear
摘要
Abstract
The bearing failure in mechanical system has strong non-linear characteristic,and its fault feature extraction is very difficult.In order to solve this problem,a new fault feature extraction method based on the Volterra series kernel under multi-pulse excitation is proposed.The nonlinear system Volterra series model is established through input and output signals of the system.Using low-order nuclear,and the time domain and frequency domain,the status of the bearing is determined and then analyzed whether the bearing in the fault states.The method is validated by taking the fault of rolling bearing in the University of Western Reserve as an example,the wavelet algorithm and multiple pulse excitation method were compared.It is concluded that the multi-pulse excitation method can extract the bearing fault features conveniently and accurately.关键词
