Abstract: With the continuous improvement of the operating speed of high-speed trains,the service environment and failure of high speed train gearbox are becoming ever more serious.At present,the domestic and foreign high-speed train gearbox has the fault phenomenon,which has seriously threatened the safety of high-speed train operation.Depending on this,some scholars at home and abroad have done some research on the causes of the failure of high-speed train gearbox.The technical methods and the results of the study on the vibration characteristics of high speed trains are summarized based on four aspects:the external excitation of the gear box,the internal excitation,the internal and external coupling excitation and the frequency characteristic.It is expected to provide technical support and reference for further study on the causes of gearbox failure.

Key words: high-speed train, gearbox, fault, vibration characteristics
