In order to effectively identify early failures locomotive running gear to improve transport capacity of heavy-duty locomotives, locomotive running gear gearbox for example, summed up the basis of the analysis of a large number of actual vibration signals, discusses the use of blind deconvolution de-noising method for extracting characteristic information motorcycle gear, which uses Fourier transform filter manipulation in the vibration signal into time domain signal, and then all of the blind signal source separation, and TSA (time Synchronization average ) compared to consider the impact of external factors, try to avoid the prediction and diagnosis errors. Through the analysis of the actual locomotive running gear vibration signals to extract the fault characteristic signal successfully, the method described in the locomotive running gear line fault diagnosis system application, not only meet the requirements of real-time and reliability of online monitoring and fault diagnosis so that the normal operation of the locomotive at the time, while showing its reliability, durability, and high degree of confidence.
