Train fault diagnosis is recognition train running state science, it is the train operation status in diagnostic information of the reflection, its research content on the train operation recognition of the diagnosis, upon its operation process inspection and the operation of the trend of the development of the forecasts. Through the correct fault recognition, find fault in the correct position, the need to repair or follow change the parts of the isolated, avoiding accidents and shorten repair time. This paper is divided into four chapters in the structure of our country, high-speed train detection and fault diagnosis in the development situation, and high-speed trains detection and fault diagnosis of the function and technology is discussed, mainly to walk line department has analyzed the breakdown of gear fault, focusing on the common forms and reasons, its fault diagnosis of time-domain diagnosis analysis and vibration signal analysis were introduced, and the gear simple diagnosis of vibration flat diagnosis method is described.
