Based on the study on key technical problems and prospect of a new generation of China high-speed trains (electric multiple unit， EMU)， the development trend and strategies are discussed in detail. The main contents include： firstly， the advanced design technology and concept of international advanced rail vehicle manufacturers used in the new generation vehicles developing process were introduced. And their respective characteristics of the core technology and its possible future technology development trend were hierarchically studied. Secondly， based on the study of domestic and foreign literatures， combined with the Chinese high-speed rail vehicle development of its own characteristics and the actual situation， some suggestions and specific analysis， which included the traction drive technology， bogie， carbody design technology and other key technical problems were put forward here. Finally， based on the development of a comprehensive consideration of rail vehicle styling trends and design principles， according to the design method of integrated design theory and multidisciplinary optimization， some specific suggestions and strategy of development for major technical challenges in the new generation of Chinese high-speed rail EMU were put forward. In conclusion， through the study of the paper， some useful suggestions were put forward for the future development of high-speed train in China.
