Abstract

With the advancement of science and technology, the railway has become an important breakthrough. Railroads can transport goods and carry people. Aerodynamics has a huge connection to the study of the high-speed railways. On this basis, the subject of this paper is the principle and application analysis of high-speed railway aerodynamics. To be specific, this study introduces the formulas and principles related to aerodynamics, and how some formulae are used in high-speed railways. The research searches for literature related to railway and aerodynamics and finds the current development status of high-speed railway. The paper explains how aerodynamics affect high-speed rail, the way to transform high-speed railways with aerodynamic knowledge. Contemporarily, there are many methods to carry out the simulation and tunnel experiments. This study also introduces some special experiments to solve special problems about high-speed railway. According to the analysis, there are still many aerodynamic problems that people need to solve, and there is room for improvement in high-speed railways.
