| Abstract: | The Trackside acoustic diagnostic technology and the nerve network diagnostic method for railway car bearings are briefly described.The application of BP network in the trouble diagnostics for railway car bearings is mainly discussed.A lot of actually measured data in field are used as the training samples to make training for the BP network already founded,and the trained network is applied in the bearings status classification,which has high accuracy.Hence,it is shown that the nerve network me-thod is an effective solution scheme in the trouble diagnostics for railway car bearings. |
