Goals and direction of CAE analysis technology of aerodynamics on high speed train in China

With the velocity of high speed train approaching 380 km/h in China and the domestic innovative technologies and design being grown up after digesting and absorbing advanced ideas from the developed countries, three issues are summarized for the developing goals and direction of aerodynamics CAE analysis technology on high speed train in China: the application of CAE analysis technology in the design of high speed railway, three significant researching and engineering goals of Computational Fluid Dynamics(CFD) analysis on high speed train and the CAE analysis technology of aerodynamics on high speed train in the future. It is clearly demonstrated that the CAE technology is playing a key role in the coming design and structure analysis of Chinese high speed train and the CAE analysis of aerodynamics is the core.
