Analysis on the Characteristics of Pressure Fluctuation for High Speed Train passing through Tunnels
고속열차가 터널내에서 받는 압력변동 특성 분석
Abstract
In order to develop a high speed train, various conditions have been considered. Fatigue strength assessment by the fluctuation of pressure is an important one. In this study, the fluctuation and frequency of pressure is measured when KHST(Korean High Speed Train) passes through tunnels in the Kyung-Bu high-speed line. And the characteristics of pressure fluctuation is analysed and formulated. The results of analysis are as follows. The train entering speed and fluctuation value are related. The pressure increasing is generated in proportion to train velocity at leading car. When two train is passing through the tunnel, the pressure value is
