Dynamic Simulation for High-speed Pantograph and Overhead-line using a Vibration Mode Superposition Method

모드중첩법을 이용한 고속용 팬터그래프와 전차선의 동적 상호작용 시뮬레이션

A dynamic simulation for a high-speed pantograph-overheadline has been performed using mode superposition method to predict contact forces between pantograph and overheadline. We can deal with non-linear dampers of the pantograph and pre-sag of overhead-line for the simulation. But, we can not consider slackness of dropper in the overhead-line. According to the simulation results, the contact forces and displacements are reasonably predicted, compared with other foreign simulation results.
