Abstract

Korean Train Express (KTX) has opened to commercial traffic since 2004 at maximum speed 300km/h, and Korea High-speed Railway (HSR-350x) was developed by Korean government, several institutes, and related companies. HSR-350x is now being investigated its performance and tested at the high speed line. In 2004 December, HSR-350x was run over 350km/h and proved its running performance. In vehicle system, the faster the vehicle runs, the more vibration increases. To improve the riding comfort of high-speed trains, it needs to devise the vibration absorber. In this paper, we propose the installation of the semi-active damper to the power car of HSR 350x and present the specification and the damping characteristics.
