Abstract

Abstract

The research methods of train aerodynamics, such as numerical simulation computation, wind tunnel tests, moving model tests and full-scale train tests, were dissertated.The research works of the aerodynamic performances of China representative train, China-star high-speed train, double deck container freight train, maglev train (magnetically levitated train) were introduced.Five important theorization formulas were put out, with the emphasis on the relations of streamline shapes and train aerodynamic performances, including streamline train head shape, car body section figuration, train configuration and car surface, the important car components that influence train aerodynamic performances enormously were discoursed, such as flow guide mantle of pantograph, outside vestibule diaphragm, car bottom with mantle structure, skirt baffle structure and flow guide plate.The whole set technology on the manufacture of streamline car shape and its applications in China were introduced.The main characteristics of tunnel-train aerodynamics were recommended.The topic concentrated upon the running safety influenced by train aerodynamic in improving speeds of five times in China and Lanzhou-Xinjiang railway suffered windstorm on more than hundred kilometers was discoursed.
