가속도/감속도를 이용한 열차 견인력/제동력 추정방법에 대한 고찰

In this paper, a method which can deduce the traction force or the braking force from the acceleration or the deceleration of the train, has been suggested. In the case of Korean high speed train (HSR-350x), the traction force and the braking forces have been obtained by using this method. It is proven that the proposed method is a very good tool in estimating the traction force or the braking force when the train starts or stops. Also, these forces can be used to calculate friction coefficients of mechanical brakes and the transmission efficiency of the traction system.
