HEMU-430X 열차 개활지 주행 시 CX 팬터그래프의 접촉력 안정성 평가

초록

The stability of the contact force of CX pantograph was assessed when the next generation high speed train, named HEMU-430X, was running in open field. For this, three dimensional flow around the HEMU-430X was calculated in open field and it was convinced that the flow velocity into the CX pantograph was 92% of the train’s speed because of the growth of the boundary layer. Then, the values of standard deviation of the contact force of CX pantograph according to the flow velocity were converted to the values according to the train velocity and compared with the values of driving test of actual train. From the analysis, it was confirmed that the CX pantograph was statistically deviated from the catenary system in case of HEMU-430X’s running in open field more than the speed of 400km/h.
