| Abstract: | Rolling bearings are important and typical parts of rotary machinery. AR model is applied to fault diagnosis of rolling bearings. AR model for time-domain signal was established. AR frequency spectral based on the given AR model was present and compared with that of the classical one. Then the condition of the roiling bearing is identified. The experimental results show that the proposed approach can identify fault patterns of rolling beatings simply and effectively. |
