차세대 동력분산 고속열차(HEMU-430X)의 중량과 가속능력의 상관관계

This study reports the relation between the acceleration and weight for the Korea’s nextgeneration high-speed train (HEMU-430X). In order to evaluate the effect of weight, the total weight of HEMU-430X was varied by 2%, and the analysis was conducted for the low speed range (less than 200km/h) and high speed range (380 km/h ? 420 km/h), respectively. It was shown that acceleration for both of the speed ranges was higher with lower weight, which indicates that the balancing speed of the train is higher than the test speeds.
