한국형 고속열차에 대한 고속(310 ㎞/h 이상) 영역에서의 승차감 예측 및 평가

The ride comfort is more important in the train speedup. Generally, it is defined as the vehicle vibration. There are many studies on evaluation method of ride comfort for railway. But the ride comfort for Korean high speed train(HSR 350x) has been assessed by statistical method according to UIC 513R. It is very difficult for HSR 350x to run at constant speeds above 310 ㎞/h during 5 minutes required in UIC 513R because of the same operational condition as KTX and the infrastructures. In this paper, the ride index at high speed above 310 ㎞/h has been predicted by using those obtained below 310 ㎞/h and the comfort for HSR 350x has been reviewed in these speeds.
