Abstract：This paper makes a comprehensive and in-depth analysis and discussion on the abnormal vibration of the main air supply unit of rail vehicles.Firstly，taking the piston main air supply unit as an example，its main composition and working principle are expounded in detail，which provides a theoretical basis for the follow-up analysis and discussion. Then，from the aspects of piston cylinder，transmission parts，motor， motor fan，anti-vibration system and frame，the possble causes of abnormal vibration of main air supply unit arecomprehensively analyzed.On this basis，through the in-depth discussion of the causes and the study of actual cases，combined with the detailed test and analysis of abnormal vibration data，a targeted solution is put forward.Finally，the efectiveness and feasibility of the solution are verified by comparative tests，which providestheoretical support and practical guidance for ensuring the safeand stable operation of rail transit，and is of great significance for improving the service lifeof rail vehicles and passengercomfort during operation.
