Permanent magnet direct-drive subway vehicles are the development direction of urban rail transit and have broad application prospects in the increasingly tense urban traffic. In this paper, a subway bogie with permanent magnet direct drive technology is designed, which has the advantages of reducing energy consumption and improving the ability of the bogie to pass through small radius curves. Through the strength analysis and fatigue test of the bogie frame, it is shown that the maximum stress and fatigue limit of the frame under each working condition meet the standard requirements, and the first-order natural frequency of the frame is 49.2 Hz, and there is no crack in the frame after the fatigue test. Through the energy consumption comparison test and dynamic line test of the subway vehicle equipped with the bogie, it is found that the permanent magnet direct drive train is relatively energy-saving by 20% to 30%, and its dynamic performance is significantly better than that of the asynchronous traction system train, which can adapt to smaller curves. It has a certain reference value for the research and design of the permanent magnet direct drive bogie of subway vehicles.
