Construction of an analytical model for Shinkansen vehicles considering elastic vibrations in the high frequency range

Abstract

To further improve the ride quality of Shinkansen vehicles, it is necessary to reduce the vibration of the vehicle carbody. A vibration analysis model is required in order to efficiently consider vibration reduction methods. In this paper, we proposed a vibration analysis model that can express the vibration modes of the carbody around 40 Hz. The validity of the model was verified by comparing the calculated results with the measured results.
