초록

Formulation of the finite element method(FEM) for dynamic interaction between a pantograph and contact wire, including non-linear formulation associated with contact wire stagger in the railway overhead contact line is presented. Penalty method is chosen for modelling contact between a pantograph and contact wire. The formulation is validated by comparing the simulated contact forces with measurements taken from 300 km/h KTX operation.
