The bogie technology of the 350km/h EMU train is one of the key parts for China high speed railways. Through analysis of the high speed bogy for CRH3 EMU train, the design conceptions and methodologies of the bogy structure and suspension systems are better understood. Technical procedures for the bogie design are carefully investigated, which includes the wheel/rail interaction, helical spring and high property rubber pad used in primary suspension, high flexible and large convolution bellows type air spring, anti-roll bar and two point control of air springs used in secondary suspension, and the elastic frame suspended structure used for traction motor. Comparison between different bogy techniques are carried out by using the dynamic simulation, roller rig test and field test, and the efficient way to raise the bogie running safety and reliability is analyzed.
