급제동 시 발생하는 연결기의 충격력 해석 모델링

초록

A simple impact analysis model for the rolling stocks is proposed using Simulink. In this model, each vehicle is represented by a 1D model. Main object of this model is define factors which make damage to coupler on special operation condition like emergency breaking. After simulation this model calculate impact force on coupler, and we can figure out damage or fracture of coupler by comparing to standard allowance criteria. The validation of this analysis model was proven by comparing the investigate report on real accident of train.
