A relationship between contact force fluctuation and pantograph characteristics is complicated in catenary suspension lines, because it depends on not only the pantograph characteristics but also the wave propagation characteristics of contact lines. This paper describes the influence of pantograph vibration characteristics on the contact force fluctuation between pantograph and contact line. In this study, factors of contact force fluctuation are theoretically analyzed and verified by computer simulation method. It is confirmed that the contact force fluctuation is proportional to series mechanical impedance of pantograph and contact line. In order to reduce the contact force fluctuation, it is effective to decrease the series mechanical impedance at the frequency corresponding to hanger span cycle or dropper span cycle.
