In recent years, the technology development in high speed railway vehicle that aims for further service improvement, ride comfort improvement and reduction of energy consumption has been continued. Therefore, design of lightweight high speed railway vehicle seat that provides good ride comfort to passenger is needed. In previous studies, it is revealed that the high frequency vibrations around 30-40Hz are occurred due to the wheel imbalance and they have a harmful influence on ride comfort. For these reasons, the objective of this study is to analyze vibration mechanism of the seat to obtain the guideline to design the seat which can reduce the high frequency vibration. Therefore, this paper describes the results of vibration experiment using two-seater seat and shaking to clarify the vibration characteristics of the seat.
