Vibration Analysis of High-Speed EMU Car Body Using Equivalent Stiffness and Shell Element

등가강성과 Shell 요소를 이용한 분산형 고속전철의 차체 진동 해석

High-speed EMU under development vibrates more than a articulated high-speed train since power units are attached on each vehicle and railway vehicle. In this study, anisotropic equivalent stiffness of a aluminum extrusion plate were calculated to know and predict vibration characteristic of High-speed EMU under development. Eigen frequencies and modal shape of high speed train vehicle were calculated. And vibration generated was predicted at each position of vehicle when vehicle was operating.
