A simulation study on predicting the current collection performance in 400km/h on establishing the maximum speed test plan of the next Korean high speed train development project

차세대 고속철도의 최고속도 시험 계획 수립을 위한 집전 성능 예측 시뮬레이션

The next Korean high speed train development project is started. In testing stage of this project, the 400km/h maximum speed test will be conducted. In Korean railway infrastructure conditions the 400km/h seems to be a critical speed especially in the aspect of the overhead contact lines. The current collection performance of the 400km/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 575km/h current collection conditions are simulated. Furthermore, review of the simulation results of the Korean 400km/h current collection conditions is conducted through comparison with that of the French 575km/h.
