This research aims at suppressing ground vibration as well as car-body vibration generated by the passing of railway vehicles by changing their suspension properties. A numerical model consists of a five-degrees-of-freedom vehicle placed on elastically supported long elastic beam is developed. A series of numerical simulation is carried out by using a random displacement input that represents vertical track irregularity between wheel and rail. The transfer functions between track irregularity and both ground and car-body vibration are estimated. The simulation results show that weight reduction of vehicles is effective for suppressing ground vibration. And the possibility to reduce car-body vibration and dynamic wheel load at a time by improving vehicle suspensions is indicated.
