분산형 고속전철 차량 현가장치의 주요강성이 차량진동에 미치는 영향

The Korean high speed train (G7) is developed as a type of the concentrated-power train. The next generation high speed train is being under development as a type of distributed-power train. The architecture of a bogie of distributed-power train differs from the one of G7. Hence, a new architecture design is required for the distributed-power train. In addition to bogie, current EMU design should be modified for the application to the distributed-power train. It is difficult to apply making EMU to make distributed-power train. Since the current EMU is a low speed model. In this study a set of design parameter study has been performed for reduction of vibration. Although dynamics of a single power car is considered, the study result may implicate overall design strategy for next generation high speed train.
