High-speed railway aerodynamics is the key basic science for solving the bottleneck problem of high-speed railway *** paper systematically summarizes the aerodynamic research relating to China’s high-speed railway *** key research advances are comprehensively discussed,including train aerodynamic drag-reduction technology,train aerodynamic noise-reduction technology,train ventilation technology,train crossing aerodynamics,train/tunnel aerodynamics,train/climate environment aerodynamics,and train/human body *** types of railway aerodynamic test platform built by Central South University are *** major systems for a high-speed railway network—the aerodynamics theoretical system,the aerodynamic shape(train,tunnel,and so on)design system,the aerodynamics evaluation system,the 3D protection system for operational safety of the high-speed railway network,and the high-speed railway aerodynamic test/computation/analysis platform system—are also ***,eight future development directions for the field of railway aerodynamics are *** over 30 years,railway aerodynamics has been an important supporting element in the development of China’s high-speed railway network,which has also promoted the development of high-speed railway aerodynamics throughout the world.

关键词： aerodynamics high-speed railway drag reduction noise reduction train ventilation train crossing aerodynamics train/tunnel aerodynamics train/climate environment aerodynamics train/human body aerodynamics aerodynamic test platforms
