In order to suppress vertical vibration of railway car body, we are under development of the primary suspension damping control system. The system enables to reduce the vertical vibration acceleration in the first bending mode effectively. In this study, the authors applied the system to reduce the forced vibration of the car body generated by bogie vibration. This paper reports the results of running test on Sanyo-Shinkansen line using an existing Shinkansen vehicle equipped with this system. The control algorithm, which controls axle dampers, is based on sky-hook control theory in one case and LQG control theory in another case. The results of the running tests demonstrated that the vertical vibration of the car body decreased by almost half as compared with the case of using conventional passive axle damper.
