The Abnormal Vibration Analysis And Fault Handing Of Df4d Diesel Locomotive

The issue stems from the using of locomotive maintenance. For improve the quality of locomotivemaintenance and ensure the stable and reliable quality in on-line locomotives, is one of the important job forrail transport safety. With the rapid development of railway locomotive system standards and requirements interms of repair and maintenance of locomotives increasing, more and more strict with quality assurance safetyawareness has become increasingly evident. In addition, in order to meet the needs of transport, improve theefficiency of locomotives in use department took the locomotive of long distance turnover and crewinter-bureau wheel ride, the locomotive with the Readiness of use, etc., but also on the use of qualitylocomotive made more high demand.In this paper, we want to solve the phenomenon of abnormal vibration, portable detector is used tomeasure the vibration intensity value, and combining with the vibration fault handling process in recent years,to develop a simple and feasible operating procedure, guide field production organization, to reduce laborintensity, improve production efficiency, the purpose of the escort for railway line transportation safety.
