Abstract
The paper summarizes start,growth,accumulation,development,improvement, and leadership of the research on aerodynamics of high-speed rails in China,which focuses on train aerodynamics,vehicle-track-bridge-tunnel coupling aerodynamics,vehicle-wind-sand-rain-snow environmental aerodynamics,pantograph-catenary aerodynamic and body aerodynamics. It is devoted to finding the mechanism of formation,building fundamental theorem,creating technical breakthrough,proposing measures to tackle aero dynamical problems which pose a threat to development of high-speed railways and safety of operation,and realizing their engi-neering application. The paper introduces a series of experimental platforms for testing aerody-namics of high-speed rails and novel experiments we have accomplished,including moving ve-hicle model tests,human comfort/vehicle body stiffness/air tightness tests under alternating pressure,aero dynamical experiments in wind/sand/rain/snow coupling environment,vision in-spection systems,experimental platform for full-scale vehicles,private/public wind tunnel and high-availability clusters for numerical simulation. Finally it discussed the ongoing research and our thoughts about further development.关键词
