A Study on the Dynamic Interaction for a Pantograph and Rigid contact wire System

도시철도 판토그래프와 강체전차선의 동적 상호작용에 관한 연구

Generally, subway runs under the ground, so it uses rigid contact wire. Pantograph and contact wire, they have effect on the contact force each other. This paper is on the dynamic interaction of a pantograph and rigid contact wire system. For this we developed simulation program of current collecting capability for dynamic interaction for pantograph and rigid contact wire. As a result, we got contact force and displacement between pantograph and rigid contact wire. This paper shows the possibility of better pantograph's suspension design and better maintaining of current collecting capability than present when suspention of pantograph is developed by theoretic result.
