도시철도 차량의 동적한계 설정에 관한 연구

초록

A structure gauge assessment is needed to ensure that a railway vehicle can run safety along a length of track without coming unacceptably close to lineside structures or equipment, or to vehicles running on adjacent tracks. This apparently straightforward question is in reality very complicated. The amount of space require for the safe passage of a railway vehicle is significantly greater than its static body profile for a number of reasons as follows : as the vehicle runs along the track, the track input excites the vehicle and it moves on its suspension. On curved track its geometric position leads to curve overthrows. A number of different approaches have been used to answer this question and some are described and specially applied to urban train by computer simulation in this paper. Th program used for calculating the kinematic and swept envelope is the VAMPIRE made in U.K.
