| Abstract: | The aerodynamic effect of trains passing throughtunnels and its principles are reviewed in this study. The mechanism ofpressure wave propagation and formation in the tunnel and the research methodsare presented, the influence of relevant parameters such as vehicle type,speed, tunnel length, and obstruction ratio on the tunnel aerodynamic effect isanalyzed. Meanwhile, the measures to reduce the tunnel aerodynamic effect areinvestigated from two aspects of vehicle body optimization and tunnel structureoptimization. Finally, achievements of study on railway tunnel influencingfactors and improvement measures are summarized, and prospect is conducted oninfluence of aerodynamic load on tunnel structure, trains, and accessorystructures, vacuum aerodynamic, and tunnel aerodynamic in windy environment. |
