A Study on Adhesion Force Modeling of Bogie Unit Braking of Advanced EMU

차세대전동차 대차단위 제동시스템 점착력 모델링에 관한 연구

In the braking process of rolling stocks, the equivalent braking force is applied to the all bogies. However, the load applied to the front and rear bogie are different in the actual commercial traveling. In the case, since the different slip situation is occurred in each bogie, it is essential to use the independent anti-slip control per bogie unit in order to reduce the loss of braking force. In this paper, the mathematical modeling about bogie unit braking is proposed and verified.
