Although the weight of passengers can be considered as an increment of carbody mass itself in design of train carbodies, it has been shown that the passengers mass does not behave as a mere increase in mass because of the existing coupled vibration between passengers and carbody. This study clarifies the coupled passenger-carbody vibration, and proposes a new model to design light-weight and comfortable railway vehicles using biomechanics. This paper shows experiment of coupled passenger-carbody vibration with a new simulator that simulates the coupled passenger-carbody vibration. Computer simulation using analytical model shows that the experimental result of vibration characteristics can be identified by the passenger model, which has one degree-of-freedom.
