고속전철 집전시스템의 동역학 해석에 관한 연구 : Ⅰ. 가선계의 모델링 및 해석

초록

The dynamic properties between catenary and pantograph of high­speed train are very important factors to affect the stable electric power supply. So as to design the reliable current collection system, a multibody simulation model is needed. In this paper, the dynamic analysis method for a pantograph­catenary cable system of high­speed train is presented. The very deformable motion of a catenary cable is demonstrated using nonlinear continuous beam theory, which is based on an absolute nodal coordinate formulation, and the pantograph is modeled as a rigid multibody. The proposed method might be very efficient, because this method can present the nonlinear properties of a flexible catenary cable and set a various boundary conditions.
