Simulation of Dynamic Current Collection between Pantograph and Catenary of Elastic Catenary Suspension System

摘要

Stable operation of the high speed train requires reliable contact between pantograph and catenary in order to offer stable electricity. But as the train speed increases, the vibration between pantograph and catenary intensifies, so the current collection between pantograph and catenary of high speed train gets more attention. A simulation model of the dynamic current collection between pantograph and catenary is established by MSC. Marc simulation software based on FEM. According to elastic catenary suspension system, the simulation is carried out under different working conditions. In this paper, with the standard deviation of contact pressure and the rate of current collection bad points as the evaluation standard of the current collection, the effect of the design parameters (contact wire tension) of catenary to the current collection quality is discussed. By analyzing the results of simulation data, this paper obtains the general law of the effect of the contact wire tension to the current collection quality.
