Wavelet analysis for location of faults on drive transmission system

Mieczysław Zając

Abstrakt

In dynamics of milles driven with electric engines issues of the drive transmission systems nonlinearity will matter greatly, especially in case of the need to conduct the identification of faults. The paper presents an example of applying wavelet analysis for investigating chosen faults in the non-linear arrangement of the drive transmission so as: appearing of backlash in mechanical connections and damaging a roller bearing. Also a case of non-linear damping in the arrangement of the mill was taken into account.
