A simulation study on predicting current collection performance with respect to the contact wire tension in 400km/h test run of the next high speed train HEMU-400X

차세대 고속철도 최고속도 시험에서 전차선 장력 증가 단계별 집전 성능 예측 시뮬레이션

In the testing stage of HEMU-400X(next Korean high speed train) developing project, maximum speed(400km/h) tests will be conducted. On present and near future conditions of the overhead contact lines, 400km/h is over the design speed criteria. The predictions of current collection performance including the percentage loss of contact(arcs level) parameter through dynamic interaction simulation of HEMU-400X maximum speed test run are described in this paper. Various simulations are conducted at the condition of two different contact wire tensions to draw the proper contact wire increasing values in the 400km/h test line under the available contact wire tension supporting condition of that line.
