차세대 고속철도의 최고속도 시험 계획 수립을 위한 집전 성능 예측 시뮬레이션

초록

The next Korean high speed train development project is started. In testing stage of this project, the 400㎞/h maximum speed test will be conducted. In Korean railway infrastructure conditions the 400㎞/h seems to be a critical speed especially in the aspect of the overhead contact lines. The current collection performance of the 400㎞/h which is predicted by dynamic interaction simulation are described in this paper. To discuss the permissible criteria of contact forces, displacements and percentage contact loss, the French 575㎞/h current collection conditions are simulated. Furthermore, review of the simulation results of the Korean 400㎞/h current collection conditions is conducted through comparison with that of the French 575㎞/h.
