| Abstract: | The paper explains the relationship between pantograph-centenary system and aerodynamic,analyzes pantograph aerodynamic model,researches the influence of the aerodynamic forces on the pantograph-catenary system for high-speed trains based on data of running test and wind tunnel test.Results show that the pantograph structure characteristic and direction of air dynamic force have significant impact on aerodynamic feature,and structure optimization design can effectively improve the performance of pantograph-catenary current collection. |
