초록

Tn this study, the crashworthy design of the full rake of KHST (Korean High Speed Train under development in G7-project) is numerically evaluated using 2-dimensional crash dynamics. The results of KHST are compared with those of TGV-K (TGV for Seoul-Pusan line). KHST shows better crashworthy behaviors after impact. Specifically, impact forces, decelerations and overriding displacements are much reduced in KHST All the design guidelines under SNCF accident scenario (collision against a movable rigid mass of 15 ton at 110 km/h) are satisfied in KHST.
