The contact force between pantograph and catenary in high-speed railways is an important index to characterize the quality of current receiving. In this paper, the EEMD-SPWVD analytic method was proposed to analyze the inherent and abnormal wavelength components of pantograph-catenary contact force (PCCF). Catenary structure Wavelength (CSW) was analyzed as SS400+ pantograph matches with the catenary mentioned in this paper, and the results show that CSW is mainly related to the parameters of the catenary. Then the DSA380 pantograph is used to make a comparative analysis, and the same conclusion is obtained. Finally, taking the irregularity of the contact wire as an example, the abnormal wavelength components are detected. The Non-CSWresidual detection method proposed in this paper is more accurate and effective than the single SPWVD method.
