Train aerodynamics is a key and basic scie nc e relating to the raising-speed of train and development of high-speed technol ogy. In China, it is a new engineering application technology to design the stre amline configuration and structure. The starting point of this project is to imp rove the train aerodynamic performance; the final goal is to carry out the produ ction of the speed-increase and high-speed trains. The complete manufacturing methods with independent intellectual property rights have been developed for th e analysis of the following subjects -train aerodynamic performance, aerodynam ic configuration, engineering design and numerical controlled manufacturing of framework beam components in the train head. The research results have been appl ied to the study and solution of a series of aerodynamic problems, which occur w hen train is running at high speed, and to the solution of the problems such as the designing and the manufacturing of bullet train. At present, all the bullet train have been designed and manufactured by using this method. Obvious social a nd economic benefits have been achieved. Therefore, there is a prospect of wide application. At the same time, the integration of multi-sciences has been reali zed in the following subjects-hydrodynamics,solid mechanics,vehicle engineer ing and the mechanical design-manufacture. It has promoted the development of t hese subjects.
