Abstract
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 mere increase in mass because of coupled vibration between passengers and carbody. This study clarifies the coupled passenger-carbody vibration, and proposes a new model to design lightweight and comfortable railway vehicles. This paper shows evaluation equipment that reproduces the coupled passenger-carbody vibration, and the experiment of coupled vibration between passenger and carbody with the evaluation equipment is presented. The experiment shows passengers' vibration has a different influence on carbody's vibration by their posture.
