Proper classification of EMU fault level is helpful to judge the severity of adverse consequences caused by different fault modes on vehicle and line operation.Based on the 3 evaluation dimensions of fault influence range,influence time and fault probability,the analytic hierarchy process is used to comprehensively score different fault conditions of EMU,and it is divided into 4 grades according to the severity.On this basis,a hazard calculation model combined with this fault classification method is proposed.Through the hazard calculation of a high-voltage traction system of a EMU,the feasibility and applicability of the method are analyzed and explained.
