Currently, the world’s major EMU manufacturers and railway operators are eager to carry out a lot of railway testing of the high-speed train bogie and optimize bogie performance according to the test data. Therefore, developing a vibration simulation system to simulate the excitation between the rail and the bogie wheel is quite necessary. In response to this situation, a novel bogie test bench of 6-DOF vibration simulation was developed, the rail spectrum reproduction technologies of wheel-rail relative vibration were studied, and many indicators of the system were optimized according to the CRH3 and CRH5 EMU wheel-rail vibration state. The results show that this technology can be used to simulate the operation of vehicles in a variety of railway state and evaluate the dynamic performance of the bogie objectively, which does not only lays a sound foundation for steady development of Chinese high-speed railway vehicles, but also plays a technological supporting role for the security and stability of high-speed train.
