In order to improve the riding comfort of railway vehicles, suppression of vertical bending vibration as well as rigid vibration of carbody becomes essential. The authors propose a system which aims to reduce the bending and rigid vibration simultaneously by introducing damping control devices in the primary and secondary suspension. Therefore, we propose a method to suppress these vibrations by using the damping control systems of axle dampers and air springs; the former one is applied for suppressing the first mode bending vibration, the latter one is applied for suppressing the rigid mode vibration. As the results of the running tests on Sanyo-Shinkansen line using an actual Shinkansen vehicle, we show that the control method effectively reduces the power spectral density (PSD) of accelerations of the carbody floor.
