경춘선 1급 신설터널에서 열차승객의 이명감 없이 주행 가능한 열차속도에 대한 연구
Aerodynamic analysis for train operation without the effect of the passenger ear-discomfort in tunnel of new Seoul-Chunchon line
초록
For the tunnel design of the first class on new Seoul-Chunchon railway, we investigated for train speeds to run through tunnels without ear-discomfort of passenger in cabin by application of numerical analysis. Also we analyzed the effect of the wind speed induced by train in tunnel that is very harmful to the workers on railroad and the effect of the air-pressure fluctuations which get the fatigue to the tunnel lining and the car body.
