In this thesis, the impact analysis for the shunting procedure using the dynamic buffer characteristics of the coupler was developed. In this study, each car was modeled as one dimensional element by using the equivalent system. After the impact, the slip exists only between wheel and rail in the braked trainset. For this analysis the analysis code named the POTAS-MSM (Power Transmission Analysis Software- Multi Slip Mechanism) which was developed for the numerical analysis of dynamic system is developed. The validation of this analysis was proven by comparing the numerical results with the results of world-famous S company which is located in Europe.

Design for automatic coupler system of Korean Tilting Train eXpress is described. In order to carry out validation & verification activities for system design, test condition is taken into account at collision speed of 10㎞/h, which is required in Safety Notice for rolling stock vehicle. The study aims at safety validation between a coupler and car body including design verification for a coupler through the identifying of system design and the evaluating of test results.
