The invention discloses a bogie overhaul training system based on simulation and a training method thereof, and belongs to the field of EMU overhaul training. By setting bogie simulation unit, fault detection unit, central control unit and fault replacement unit, the structure simulation and fault simulation of EMU bogie are realized effectively, and the training of students on bogie structure, component principle, component connection form and cognitive training and physical operation training of bogie fault are realized. The maintenance training system of the present invention, so that thatstructure is simple, Easy setup, High control accuracy, the rationality and systematicness of the training methods have been enhanced, At that same time, the physical train and the theoretical training are complete indoors, the efficiency and the quality of the bogie overhaul training are greatly improved, the cost of the bogie overhaul train is reduced, the technical ability of the personnel on board the EMUs is improved, the stable and efficient operation of the EMUs is guaranteed, and the bogie overhaul training has excellent application and popularization value.
