Abstract

The high-speed railway EMU obtains electric energy through sliding connection between pantograph and catenary. A reliable and stable connection between pantograph and catenary is helpful to improve the current collection quality of EMU, reduce the off-line rate of pantograph and catenary, reduce the arcing rate and improve the service life of pantograph and catenary. This paper carried the modal test experiments of CX-G pantograph assembled by China CRH 400 EMU under different working conditions, the effects of different raising height and static contact force are studied. Data shows that the resonant frequency of first order operational modal will change with pantograph rising height and static contact force, which should be considered in catenary design and pantograph operation parameter configuration to optimize the relationship between pantograph and catenary.
