机车车辆滚动轴承故障BP网络诊断方法

BP Network Fault Diagnosis of Ball Bearing in Locomotive and Cars

神经网络故障诊断技术已成功的应用于航空航天领域，但在铁路系统应用极少。文中介绍了神经网络故障诊断理论方法，并以ＢＰ网络为基础，实现了机车车辆滚动轴承的多故障诊断。

Neural network is widely used in machine fault diagnosis in the field of mechanical engineering,but rarely used in the railway system.In this paper,BP neural network fault diagnosis technology for ball bearing of locomotive and cars is presented.Diagnosis results show that BP network diagnosis technology is very effective.
