The establishment and validation of pantograph and overhead conductor rail dynamic simulation

Abstract

Overhead conductor rail which has become the main form of the overhead catenary, is widely used in China’s urban rail transit. In order to understand the vibration behavior of pantograph and conductor rail, it is necessary to carry out the study of the interaction between pantograph and conductor rail. In this paper, we will give a simulation model and calculation method of pantograph and conductor rail at first. The simulation is based on a 3-D finite element model of the conductor rail and a lumped mass model of the pantograph. The main modeling equations and ideas are provided in the simulation process. Finally, a dynamic test for pantograph and conductor rail has been designed for validating the effectiveness of the simulation.
