Abstract:

Bearing fault diagnosis is a key research content of condition-based maintenance for machineries. Because of noise interference, incipient bearing fault is always difficult to be found. Traditionally, a large number of filtering algorithms used are limited to the cases of Gaussian noise or linear operation. In this paper, the adaptive Myriad filter and alpha stable model are elaborated. Myriad filter is a non-linear filter, which can be effectively applied in impulsive environment. The order of Myriad filter can be determined by alpha stable model. Finally, both laboratory fault data and real fault data from a public data set are used to verify the efficiency of the proposed method.
