| Abstract: | This paper proposes a program of acoustic diagnosis for bearing fault which meets the need of the in-transit railway truck rolling bearing fault detection.A fault diagnosis method of analysing with the characteristic parameters in time-domain and frequency-domain is discussed in detail.The experiment results proved that this program could detect the railway truck rolling bearing fault with a high precision. |
