CRASHWORTHY DESIGN AND EVALUATION OF KOREAN HIGH SPEED TRAIN

초록

An intensive study was conducted for crashworthy structural design of Korean High Speed Train(KHST) recently developed. Two main design concepts are setup to protect both crews and passengers from serious injury at heavy collision accidents, and to reduce damages of the train itself at light collision accidents. A collision against a movable 15 tons rigid obstacle at 110 kph and a train-to-train collision at the relative velocity of 60 kph were selected as accident scenarios for the heavy collisions from the train accident investigations. A train-to-train collision at the relative velocity of 16 kph was used for the light collisions.
