For high-speed operation on an electric railway, the contact loss of the pantograph is one of the important subjects. In order to investigate the relations between the contact force fluctuation of the pantograph and the wave motion of the contact wire, theoretical analyses and experiments are carried out. From the results thereof, at a frequency at which the contact wire can be regarded as a string, it is confirmed that the magnitude of the contact force fluctuation is proportional to the vertical velocity amplitude of the incident wave into the pantograph. The values measured in these experiments agree well with the theoretical results. In the case that the wave of the contact wire is reflected completely at the support point, the contact force fluctuation is mainly caused by the wave. It is expected that reducing the degree of wave reflection of the contact wire will lead to the decrease of the contact force fluctuation and contact loss.
