In this paper, numerically evaluated is the regulations for crashworthy design of the Korean standard urban train suggested by KRRI. The 4-car consist of K-EMU(Korean Electric Multiple Unit) train developed in recent is analyzed under various collision conditions such as normal coupling, heavy shunt, light and heavy collisions. The collision conditions are assumed as K-EMU collides against another stationary one at 5 kph, 10 kph, 25 kph and 32 kph. According to the numerical results and bibliographical study, it is necessary that the regulations by KRRI be complemented from crashworthy point of view. Furthermore, the K-EMU train is recommended to adopt a new coupler with an additional energy absorber or a mechanical fuse.

In recent years, There are many consumer needs and safety regulations for high performance vehicles. For this reason, Various stability assessments are being performed to meet the regulations for the suspension corner module impact tests. The objective of side Impact Test for the suspension corner module is to assess the vehicle stability caused by unstable driving conditions such as Kerb Strikes. Side Impact Test has been performed on the full vehicle condition so far. Recently, Some components and module manufacturers are making an effort to develop the proper impact test facility for suspension corner module. In this research, experimental assessments were carried out on the suspension corner module using newly designed and manufactured impact test facility through the benchmarking of the existing Impact test facility of automobile maker Adding to this, we modelled the impact test facility and suspension corner module using Finite Element Software to correlate analytical results with experimental to verify the reliability of analytical approaches.
