| Abstract: | The paper presents a wavelet transform based method for fault diagnosis in roller bearing.The orthogonal bases of wavelet are used to translate vibration signal of roller bearing into time scale representation.By making an envelope spectrum analysis of wavelet coefficients of high scales,which represent high frequency signal,the fault in roller bearing can be detected and fault pattern can be identified validly. |
